Hiya,
I have a Lexus IS200 Navigator SE, manual 1999
My car decided to go into limp/safety mode yesterday. Engine light constantly stays on and the traction control light is constantly turning on and off. Now only revs to 3000rpm before limiter kicks in. Although works just fine upto this point. Have a friend who has a garage and has diagnostic software. Had the car plugged in and the following error code was reported:
P0105 Manifold absolute pressure barometric pressure circuit malfunction.
Am guessing one of the pressure sensors have had its day. My friend mentioned it was the inlet manifold but I am not 100% sure how he came to this conclusion, as it did not say this on the print out. Tried locating the sensors but havent had much luck and I dont have a manual. Am currently searching for a CD version on ebay.
Just wondered if anyone else has had this problem, or knows what maybe wrong, which sensor? etc. Dont want to pay dealer fees unless its a last resort.
Any help much appreciated, thankyou.
