IPC Replaced - now have check engine light
I just replaced the IPC sensor on my 2003 E350. It had 290,000 miles on it and it was the original. I did it because my idle will slowly get faster and faster. A quick kick of the accelerator and it goes back to normal, but then it will slowly take off again.
It was not too bad a job. You definately have to get the intake hose out of there. An 8mm on a swivil joint connected to this special tight access palm ratchet from Harbor Freight did the trick. Then you have to use a 5/8 crows foot on a wobble extension to unscrew the old sensor out.
Does anybody want to speak to putting the new one in? There is an o-ring at the base of the sensor's threads. I put a little oil on this and screwed the new one in tight with a 3/4 inch stubby wrench. Then connected the wires back up. I had to pull the wire connector a bit to make it reach since the orientation was 180 degrees turned from the original sensor.
Here is the sucky part. When I buttoned it back up the check engine light came on and the idle problem wasn't fixed. I feel like I just spent $80 to turn on my check engine light. Would something I did cause the check engine light to come on? Is there a way to turn it off without paying someone with a scanner to do it? How about that idle problem, any ideas? Thanks!
