Vollvo S40 "Failure in Engine Electronic System"

**ricsan07** · February 24th, 2012 10:34 AM

What do you think?????? I had my Volvo S40 1998 model engine wash, right after I noticed the car hardly move and obvious drag in the engine. It starts and run but the drag when you drive is terrible and makes engine hamming hard. There was a sign at the dashboard, the lambda sign, which according to manual was 'failure in the engine electronic system'. I want to know which part in the engine needs replacement? Thank you for you help. You may reply as well at ricsan07*yahoo.com

water must have went into a sensor or terminal

baka airflow sensor

dunno

kailangan na ng OBD to read the ECU kung ano ba problem.

kaya mahirap mag engine wash ng sasakyan with sensors.

Thank you Uls. Sorry promdi ako,, aling terminal yun?

there are a number of sensors sa engine. every sensor has a terminal connected to it. all of them goes to the ECU

sa pag washing may nabasa na di dapat mabasa

just hope nothing happened to the ECU

Thank sa reply Crazy_boy...tama ka, di alam nung nagwash din... I have my personal OBD, di ko lang alam gamitin, pero my indicator nasa dashboard as stated, I'll try suggestion ni Uls sa sensor. Volvo S40 lancer ang parts nyan, kaya hanap kolang which part there was the sensor or terminal as suggested by Ils.

I would think it's just one or more of the engine or transmission sensors that got wet which is giving you the problem. Once the sensors dry out, it should go back to normal.

BUT you might have to reset the ECU for that to happen.
