What the heck is this????

I ran self diagnostic on my Jeep and the hayes manual tells me that my automatic idle sensor is bad...can someone please tell me what the heck is going on? Is it a huge problem? do I need a new one and if so can I replace it myself? Thanks again guys.

When I run the diagnostic on my 93 yj I get a 33 (Air conditioning clutch relay) then 55 (End of Code Output). Guess what no A/C on this vehicle. Let me guess... Your vehicle does not have an automatic transmission. I'm assuming you got a 25 code (Automatic Idle Speed (AIS) circuit). If the sensor is not available it probably shows up as an open circuit and gets recorded in the code memory. I'm just guessing however, I don't know for sure that the AIS circuit is for an automatic transmission. A couple of other things to check. If your engine has about 82,500 miles it could be the Emissions Maintenance Reminder(EMR) telling you it is time to change the Oxygen sensor. I think you have to have the diag tool to reset that. Your dealer can reset it (you will probably have to convince him you replaced the O2 sensor and buy him a beer.)

self diagnostic?? how do you run it?

There comes a time... In every mans life, when decisions... have... to be made. Whether to toil, to labor, or just plain piss your days away.

The check engine light should then blink out any error codes stored in the computer. You can either look up the codes in a repair manual or post them here and I or someone else can look it up.
