On almost all cars any sensor unplugged can turn on the check engine light.
Check to see if you accidentally disconnected the wiring to the sensor at the rear wheels
Replacing the water pump will not cause the check engine light to come on. Either it is a coincidence or you have accidentally disconnected a wire or damaged a sensor somehow.
Maybe when new thermostat installed a vacuum hose was disconnected? Or perhaps a sensor was disconnected and was not noticed. I would do a visual check first looking for Hoses off and unplugged sensors. Then get the car scanned (free at autozone) Is the check engine light on ?
Where is the light sensor is on 2003 C 320, and how to check it. My dash board message says "1 Malfunction" check light sensor. Please help.. Thanks...
The oxygen sensor is one of many things that could turn the check engine light on.The oxygen sensor is one of many things that could turn the check engine light on.
you should check your transmission, i have the same problem and it ended up being one of the gears being burned out, even after i disconnected the plugs, it could have something to do with a sensor but then again this is my experience
The cam sensor is inside the distributor and tells the computer the rotational location of the camshaft.
Check your engine codes, your airbag is disconnected or blow or not installed?
There is not one sensor. All the ECM sensors are tied to the check engine light.
That is what the check engine light is for. It informs you of a failure.
If it is bad the check engine light will come on and set a code for that particular sensor.
either a bad sensor somewhere, or a connection is disconnected
Check your ABS sensor
Yes, an unplugged sensor can cause a check engine light.
You might need to change your O2 sensor. If the check engine light came on there will be a code set in the ecm. Have your local auto parts store read the codes for you. The codes will help you find what is wrong. Something may have gotten disconnected when the oil change was done.
It has two. VSS1 is located in the combination meter(gauge cluster) in the dash. I believe it cannot be replaced separately of the combination meter. VSS1 is located on the bellhousing of the transmission on top of the passenger side. There is a cable that connects the two that will cause a check engine light when disconnected or broken.
replace the bad sensor and it will turn off.
its the sensor located in the intake, called intake air temperature, when disconnected check engine light come on and shifts hard into drive and reverse check for bad harness or unplugged.
if you look just under the distributor you will see where from right to left you have a radiator hose, heater hose, then two sensors, the sensor furthest to the left is your coolant sensor, I was troubleshooting mine earlier and started the car with it disconnected i got check engine light with p0118 (coolant temp sensor) so there ya go
To reset the check engine light on a Hummer H3, the problem causing the check engine light should be repaired. If this does not fix the problem, the battery may need to be disconnected and re-connected.
Bad coolant sensor or faulty wiring to the sensor.
Replace the faulty speed sensor and the light will reset itself after a short drive.
one reason can be,is that the abs sensor were disconnected or ripped off. take off your front tires and check for any unplugged sensors or ripped wires Have the system checked for codes so you know what to look for.
