How do you bleed the brakes on a 2002 ford focus? and what order do i start?
on vehicles like the focus it is fairly easy to bleed the brakes but to do it properly you will either need a vacuum brake bleeder or to enlist the help of a friend as it is a two person job if you dont have the brake bleeder. it is important to bleed the brakes completely every 25000-30000 miles or whenever you have the friction material replaced. this removed the old brake fluid that has been heated and cooled numerous times throughout its life and removes contaminates from the braking system that could cause it to fail later in the vehicles life. start by making sure the master cylinder reservoir is full and leave the cap off of it. it is very important to not let the master cylinder run out of brake fluid during the entire bleeding procedure as it will introduce air into the system which is the opposite of what you want to do. once the master cylinder is full, go to the wheel that is furthest away from the master cylinder and open the bleeder valve, let the fluid run until it becomes clear and there are no bubbles checking the master cylinder every so often to make sure it is not running dry, top off as needed. when that wheel is done close the bleeder and move to the opposite side wheel and do the same thing again, followed by the front wheel furthest from the master cylinder and finally by the one that is closest. when fluid runs clear to each of those bleeders it is time to have your recruited friend get into the vehicle and with the bleeders closed have him depress the brake pedal slowly ( 3 second count) until the pedal feels resistance. once he has this resistance have him hold moderate pressure on the pedal and open the furthest bleeder slowly and verify no air is coming out and it is just clear fluid. close the bleeder and repeat in same sequence as before. once this is done with the key off the pedal should feel quite solid and not fade under foot pressure. start the vehicle and make sure things feel normal and you should be all set. if it does feel a bit spongy under the foot you may still have a small bit of air in the system, repeat the above procedure until the pedal is where it should be and button things up.
How do you check fuel pressure on a 2001 ford focus?
Ok, There is two ways to do it. One, U need a FORD scaner and go into somethng called PIDs(parameter identification data) You will need to chose FP sensor and read what is the presure, this method is not accurate because the sensor could be foulty. the other method is to buy a kit to conect a fuel pressure tool and read the value. this is more acurate and better in my opinion. This vehicles do not have a conecting devices to hook a fuel presure tool. good luck
2000 Ford Focus error code B2159 output short?
One day while driving the car shut off without any symptom or warnings and would never start again. Cranking is sluggish for whatever reason, battery is fine. Coil pack and crank sensor are also fine, plugs and wires are new. Tested the car on a machine for error codes and got "B2159 output short-ground csm-vsm". I heard this relates to the anit-theft system?? What exactly does this mean? If there is a short on the ground wire, where do I look? Is there a place where this typically occurs on a Focus? Please help.
What is the difference between a camshaft and a crankshaft?
Crankshaft: well this part of an engine is a shaft as the name suggests on which all the units of a engine are mounted. When the piston move or reciprocate up and down this movement is transferred down to the crankshaft by the piston rod and crank to the crankshaft. Imagine ur legs pedalling a bicycle ..so instead of the pedals u have the connecting rod and ur legs are the pistons. So the reciprocating movement is converted to a rotary motion of the crankshaft. Another example is a diesel gensets u have at villages which u crank up with a turning handle to start. U through the lever are rotating the crankshaft to impart initial driving momentum to the engie.Camshaft: as the engines work they need to breathe out exhaust gases and take in fresh air ( charge) for the next cycle to take place . All these processes need to take place at a designated time wrt each other. These processes are timed through opening and closing of valves and actuation of fuel pumps through a actuating mechanism which is triggered by movement of the crankshaft. The camshaft comes into picture here. The Crankshaft drives through a belt or chain drive the camshaft on which the inlet/exhaust/ fuel pump cams are fitted for each unit when the crankshaft rotates it in turn rotates the camshaft which precisely actuate the valve and fuel pumps.For the relationship between the two. In a 4 stroke engine camshaft rotates at half the speed of the crankshaft and in a 2 stroke engine the speed of both the shafts is same
What does a mass air flow sensor do? Can a car run without one?
Mass Airflow Sensors (MAF) report the amount or density (Mass) of the air entering the engine to the Powertrain Control Module (PCM).There are various designs of MAF sensors, but the most common by far is the hot wire MAF sensor. The hot wire MAF has two wires. One wire is heated and the other is not. The computer (PCM) calculates the mass of the air entering the engine by how much current is required to keep the hot wire about 200 ℉ hotter than the cold wire. When the temperature difference between the two sensing wires changes, the MAF will either increase or decrease the current to the heated wire. This equates to more air into the engine or less air into the engine.While the vehicle may run with a dirty or broken MAF, it will not be efficient and may cause mechanical damage to the engine due to running in a lean condition.A failed MAF sensor may not send any airflow information to the PCM. This prevents the PCM from accurately controlling fuel, which will result in an engine that either will not idle or will idle roughly. If the MAF is still sending information, but the information is wrong or garbled, the PCM will send the incorrect amount of fuel through the injectors. This will lead to a consistently rich or lean condition. You will notice this as a change in fuel consumption or black smoke coming out of the exhaust pipe. In either case, replacment of the MAF is required.A dirty MAF will give symptoms of rich at idle and/or lean under a load. A MAF that has a contaminated hot wire can come from spider webs, potting compound, oily dirt that comes from an over-oiled reusable performance air filter, or other sources. Anything that acts like insulation on the hot wire will cause this issue. This is not a failure of the MAF, the fix is as simple as cleaning the MAF sensor with an approved MAF sensor cleaner (Yes, this is a real thing).As a short term, limp home thing, yes some vehicles can operate with a failed or disconnected MAF. But it is a needed part for fuel injected engines that were designed with one in the control system. Some injection control systems do not have a MAF, and no carburated engines have them.
How tight engine coolant temperature sensor?
The coolant pressure isn't likely to be more 15 to 20 lbs. so that's not a consideration as far as tightening goes. If you apply a good sealant (permatex or equivalent) to the threads then tighten using the pressure you can apply with the fingers of one hand with a standard end wrench should be sufficient. Don't judge the correct tightness by what it took to get the old one out because remember it was in position for a long time, enough for whatever sealant was used to harden considerably. If you want to be more precise, Google the torque settings for your engine to find the factory specs.
Bad Fuel Pump or oxygen sensors (o2)?
All the codes you're getting can be caused by the rich condition. Lots of fuel fouls the O2 sensors like it does the spark plugs. The computer uses the output of the O2 sensors to calculate whether the EGR is operating properly. The test it runs could be skewed. Also there is a possibility that the EGR (DPFE) sensor is full of carbon. You need a fuel pump pressure and volume test to see if the pressure is too high. You can also pull the hose off the pressure regulator on the fuel rail to see if it is leaking gas. Common ford problem. It allows extra gas to be pulled into the intake making the whole system waaaay rich. After you locate the problem you need to clean or replace the spark plugs and disconnect the battery for at least ten minutes. This allows the computer to reset the long term memory which controls the fuel mixture. Hopefully the oxygen sensors will clean up on their own at cruising speed. When you check the regulator make sure you pull off the vacuum hose then just turn on the key. Then look to see if gas runs out of the little tube on the regulator. It's not a good idea to do this running for fire hazard reasons. If it does leak, make sure to wipe up all the spill or let it dry before cranking the engine. Another possibility is the EGR valve staying open at all times, although the engine wil usually run badly and at high idle. The low vacuum on the regulator in this situation will increase the fuel pressure but not usually enough to overcome the large vacuum leak(lots of air going in). Good luck and post back with updates.
Where is the plug in for the OBD II scanner in a 2001 Ford Focus?
The OBD II plug in is located directly under the steering wheel beneath the dashboard plastic. If it's not there, it has a compartment access on the bottom of the dashboard. All OBD II access plugs are located within 1 foot of the steering wheel.
2001 Focus check engine light?
Auto Zone just wants to sell you something that probably won't fix the problem. All these people that say "go to autozone" don't really know what's going on themselves. There are about 15 things that can set this code. Excessive Fuel Presure Leaking Fuel Injectors Leaking Fuel Presure regulator Low Fuel Presure or running out of fuel Vapor recovory system Air leaks after MAF (Mass Air Flow Sensor) Fords are very particular about air flow. Did you just have an oil change? They may not have put the air box back on completely tight. Vacuum Leaks PCV System Leaking diaphram or EVR Engine oil over fill (did you just have an oil change) Cam Timing Cylinder Compression Exhaust leaks. Now after listing all of that, it is more likely just a little clitch in the system or as stated earlier if you just had an oil change, when they were checking everything they didn't get it all back tight. What usually happens is the engine ran lean for a brief few seconds and the O2 picked up on it. We never condemn anything the first time the customer comes in with a 171. We clear the light and send them on their way. 99 times out of 100 it was just a clitch. May be an early warning sign but not necessarily a real problem yet. One thing most auto owners neglect is their Fuel Induction Services. The cost about $129 or so and can prevent a ton of problems including injectors clogging up which in turn is related to about half the stuff I listed here. If you buy an induction service from a local shop you might get them to turn the light of for you without an extra charge. The big chains probably won't do that.
