Hi!
I had this code come on now for a while, oc2 was change and code P1070 in 01 & 02 keep coming up, usually after the car has run for quite a while. I saw on the tech post references to the air flow censor, and my guest was of the egr valve or the thermal switch to the valve, is this correct and can you tell me exactly what it may be and the fix?

Thank you

use the SEARCH engine on this forum, type in P1070 and you'll get; instructions and where to buy plus additional diagnosti info.

Thanks Ethan

Seems that it's the same thing that I just fixed on a Grand Marqui, just needed some cleaning of air intake. I would hate to replace the air flow meter unless I have to
Thank again

I had the same code and Check Engine light go off on my 1998 C-230, the big thing for me was the funny way the transmission was acting.
I didn't read or check adaptation values and gambled on the MAS sensor, which in deed did fix my problem.

I always thought intake cleaning or repairng of the MAF/MAS sensor wouldn't work, but I did read on one forum ( maybe here or at www.club202.com) someone posted directions on how to attempt a repair on the MAF/MAS.

So far so good my light hasn't come on for afew days after puting the oc2 censor. No isues with the trainy so far! By the way no free speech at (www.club202.com)

What is an oc2 ??
