I have a 2004 Mercedes C230 with the 1.8 L engine. The IAT is new and the wiring from the IAT to the ECM check out for continuity. I still get the engine code 0110. Is there a way to verify if the IAT is good?

Do you
have the same problem?

Thank you! One more thing is that there are 4 terminals on the connector to the combination MAF/IAT senor. Do you know which two are for the IAT?

See schematics attached. The IAT is shown on the first one at the top right, if I recall correctly. The MAF is shown on the second at the top right.

Those are great diagrams, but I just can read them when I blow them up. Can you send pdfs to miec@netzero. Net?

Thanks.

Yes. I'll send both jpegs and pdfs. I enlarged them to 7500 pixels wide, too. They're huge.
