Engine light is on but no codes


Asked by May 31, 2016 at 09:53 AM about the 2007 Chrysler PT Cruiser Base

Question type: Maintenance & Repair

I'm completely lost! My check engine light is on and was
saying that I had a bad o2 sensor. But now, it won't throw
any codes at all. However, when I push on the gas, she'll
go but once she hits 2 rpms she just sputters and jolts.
Also, checked tranny fluid and it was fine but I just noticed
that tranny fluid is all inside driver side wheel well, on the
inside of my hood, ok the outside of the grill, all over
inside the hood actually, and when I looked under the car,
it appeared to be leaking all over under the drivers side.

First the 02 sensor can be slow and cause the check engine light to come on. reading the live up stream 02 sensor with a good scanner can determine how bad or slow it is reacting.. But FIRST it seems you need to correct the bad / leaking transmission line, or possibly the the radiator transmission cooler is allowing the fluid to blow back all over the chassis, look under the vehicle inspect for the origin of the leak! Once this leak has been corrected, continue with the 02 sensor check out. Regards
