So turned the engine off left it for a few seconds turned it back on revs when back to normal but the epc light and engine light stayed on but car worked fine took it right to the mechanic he read the codes and checked it over and said everything looked ok and said maybe it was a one off cleared the codes all was well. Over the next week or so the engine light and epc light would come on but the car would run fine and the lights went off after a while so fort nothing of it as other days there would be no lights at all. Till today driving home and the very same spot on the road where it went into limp mode before done it again with the same thing even pulled over in the same place as before. The codes were fault one 16524:035 o2 sensor circ,bank1-sensor2 no activity detected fault two was 17961:035 altitude sensor signal/intake manifold pressure implausible ratio fault three was 17912:035 air intake system leak detected. Any help would be great seems the mechanic is lost too.

Sidom Veteran / Moderator Sep 11, 2023, 1:46 PM Post #3 of 4 (935 views) Re: car going into limp mode Sign In As HT said, we don't have this car over here so there is no help for us in our databases. That being said, it is rare for a car to have 3 or more sperate circuit failures (codes) at the same time (unless it was hit by lightening) ;). So usually when you have 3 or more codes, there is something common to all 3 causing the problem. It is possible to have 2 problems. You could have a vacuum leak & a bad O2 or a bad O2 causing the lean & possible map codes. The 1st thing he would want to do is look at the fuel trims at low & high speeds to see where the lean problem is. If the O2 is stuck lean (no activity code) then if he does a "propane enrichment test", this will test for a bad O2 even with a vacuum leak or false air problem (within reason) If he isn't familar with these, there is a ton of help on "how to" on youtube. rick.p New User Sep 11, 2023, 1:58 PM Post #4 of 4 (932 views) Re: car going into limp mode Sign In In Reply To My bad didnt notice it was a US car site been very helpful either way many thanks (This post was edited by rick.p on Sep 11, 2023, 2:01 PM)   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
