After testing the MAF sensor, changing the PCV & CO sensors, I still get the check engine light, 1999 ford explorer sport 4.0 SOHC 6 cyl I've read to check the intake manifold and then go fu


What is a CO sensor? Never heard of it. a 1999 OBD2 ford has approximately 1600 possible fault codes most of which can turn on the light. If you dont know which one is turning it on, you are guessing randomly which is expensive and usually unsuccessful. get the code(s) and then diagnose the possible causes. The vehicle you list (99 4L explorer) rarely had injector problems. Much more common were EGR sensor(DPFE) sticking at voltage, evap problems, misfires, and lean conditions due to dirty MAF, or vacuum leaks. get the fault code, or you will not fix the problem.

Hi. i have a 2001 ford escape. i have just had completly serviced. i got it home and a couple of days later the check engine light came on. so i took it back and he couldnt find anything wrong. however he...


Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

I was driving and explorer just shut down the power steering went out


Hi...I am assuming it will not restart? This is typical of a fuel pump that has used its life span. Is your check engine light on? If so..get someone to read your computer codes to see whats going on...AutoZone will check codes for free.

1996 ford explorer engine sounds like it is about to die when idling


You need to open hood look at the engine see if you can recognize any vacuum leak , it will sound like a whooshing sound, and check the PVC(hose going to valve cover) it can be clogedif not have autozone read your obd2 to find out what is the code?

Replaced the O2 sensor unit and the ECM(programs installed) but I'm still getting CHECK ENGINE LIGHT(P0001). what is the possible problem and how can this be resolved?


P0001 Fuel Volume Regulator Control Circuit/Open The above code is about an oxygen sensor code for the heater circuit located in bank 1 sensor 1. (bank 1 is at exhaust manifold by the #1 cylinder head, bank 2 is on the 2nd cylinder head. On some engines, both exhaust manifolds could have one oxygen sensor each side and the 2nd cylinder head will have the sensor 2). On the oxygen sensor itself, it has 4 wires which are color coded. Two of wires are for the heater circuit that heats the oxygen sensor to make it reach optimum operation quickly. Those 2 oxygen sensor heater wires could be shorted between the sensor and the ecm (engine computer) or other engine components.
oxygen%20sensor%20heater%20copy.jpgThe common fix for this code is to check the integrity of the heater wires. Check the wires for insulation and routing which could be loose or touching a hot exhaust that can short the wires. If the engine has too many miles, it is possible that the heater circuit inside is worn and shorted which needs a replacement of the oxygen sensor. If you have a DVOM, you can also test the continuity of the heater wires from the oxygen sensor to your computer pins.
More detailed fixes will be provided as soon as you give the symptoms of the obd2 trouble code. ATS will provide the wiring diagram so you can trace the color coded wires. Use an obd2 code reader or scanner so you can access this obd2 trouble code. When you have this obd2 code list, use it as a reference and give the code to ATS. We will then send you all the possible fixes for the obd2 trouble code. ATS has lots of fixes for obd2 gm codes, obd2 ford codes, dodge obd2 codes and all obd2 import codes such as Toyota obd2 codes, Honda obd2 codes, Nissan obd2 codes, etc. All fixes for this obd2 codes are guaranteed or your money back.
Important TIPS about Oxygen sensor:
The oxygen sensor content of the exhaust gas indicates when the engine mixture is operating lean or rich. When the oxygen sensor detects that the engine is operating rich, the signal voltage is high, and any decreases in the signal voltage means the engine running is lean. The engine computer supplies a reference voltage like one volt or five volts, and then shows the change in the sensor return voltage as the sensor's resistance is changing. If you have connected everything properly, when you crank the engine, you should see the check engine light coming out.
Unheated oxygen sensors rely on the heat of the exhaust gases to reach the working temperature, therefore they might start to cool down while the engine is idling and revert back to a default air-fuel ratio setting. This type of sensor usually has a single wire connector, though others have two. Unlike the fuel pump relay, the 02 sensor heater circuits have a separate fuse for each sensor and grounds, which are controlled by the engine computer.
To read a voltage across the heater, one side must be connected to (+) and one side must be connected to (-), which is accomplished by the computer or a transistor. It can read 12V between each wire and a separate ground if it was connected to positive and the other was not yet connected to ground connection (for details, please contact ATS).after you replace oxygen sensor you have to drive for so many miles before it resets its sef
