You have a bad 02 sensor after the catalytic converter.
you can also go to O'riley Auto Parts or some other auto stores and the will also check your computer for u for free. TimAnswerTech-2 diagnostic tool at a dealer or auto repair shop.
The speed sensor is at the back of the transfer case behind the handbrake. Series 2 can use a signal from the auto trans.
A sensor could be bad. Take it to Auto Zone and have them run a diagnostic. It's free and they usually have the parts on hand.
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
It depends on what type of signal the meter needs/ voltage range. The signal would have to intercepted form the transmission sensor, wheel speed sensor or the signal going to the instrument cluster. An alternative is to get a separate GPS based/speed sensor, auto-meter sells one to use for their electronic speedometers due to different transmission, wheel sizes combos available when a car is customized. It might be better/cheaper to due it that way.
that would come up on your on board computer, test it with a obd2 scanner an trouble codes will come up, if your car still runs they will test it free at auto-zone or murrays
This indicates that you have a malfunctioning oxygen sensor. Take your jeep to one of the name brand auto parts store and they will have a reader that will verify this and sell you a new sensor. That will most likely take care of the problem.
could be PO118= PO118 Engine Coolant Temp Circuit high =coolant temp sensor. Take to Auto zone or Advanced Auto (if in your area) and they will run a free diagnostic and tell you the code and what the issue is. Mine was the PO118.
get an engine diagnostic check from a trusted auto shop. check fuel injectors, and, if equipped, iac motor and tps sensor. Run a compression test.
Cooling fan operation in determined by the Powertrain control module using inputs from the Coolant temperature sensor and A/C request signal from A/C system.
quite possibly....the check engine light is a universal signal saying "something is wrong". Take the car to auto zone and have them use the hand held diagnostic. Once used, the diagnostic will pull up a code from the engine's computer that the auto zone employee can pull up. Once the code is looked up for that particular vehicle, itll tell you what the light came on for.
Either use a diagnostic computer (go to your local auto parts store, they should have one) or disconnect the battery for 20 mins or so.
