P/N and part sources for Air Temp Sensor (on IC) for '89 200Q

[Larry C Leung]

Thanks Jim (I think).

I'm sorta convinced the sensor isn't working right (don't know
how they could fail, it's just an RTD, right?) that's why I sent
the post to Scott J and SJM to see if there's a connection to
the bad cold starts. If there is, then I'd be willing to bet that
the sensor is unreliable. Plus, I cleared codes twice and
it came back as the only thrown code (although the check
engine light did NOT flash as far as I could see). I could attempt
to re-wire the blame thing, at the price you're mentioning
for the sensor, it would be worth a total rewire job.

Thanx for you help,
