Hello all,
I am new to the forum, having just purchased a '99 VP. I was wondering if there is an owner proceedure for cyling the onboard computer for error codes? I can do this on my Grand Cherokee by cycling the ignition three times and a code(or no code) will appear on the readout.

I just had the check engine light come on...the oil was low from the previous owner. I changed the oil and checked all of the other fluids and topped them off. The light is still on. I am thinking that it may be an oxygen sensor, but would like to access the trouble codes myself, rather than take it to the steelership, I mean dealership

Any information that you can provide would be greatly appreciated.

 

I used the scan tool and got these codes:

P1000 - fuel/air metering aux. emission controls
P0442 - EVAP emission control system leak
P1111 - Manufacturer control fuel/air metering

Does anyone know what these equate to? I am guessing that I have a faulty O2 sensor, but it did not indicate what bay or location.

 

Thanks for the link Bigdreams...do you know what P1111 means? It was not on your list, but I think it may have something to do with the MAS.

 

I have the check engine light on mine too, how do you get the code to pop up on the information diplay?

 

i also have P1000 showing up. (fuel/air metering aux. emission controls )

Does anyone have more info on this issue, and possible remedy??

Thanks.

 

I cleared all of the codes and all is well for the time being. I am going to check all of the sensors one at a time to see if I can find the culprit.
