Hi,
The Check engine light on my '95 E420 keeps returning. I get a Code 2 which seems to show a problem with the temp sensor. The indicated temp has always been normal and seems to be operating correctly. I reset the Code and it returns after the engine has been shut off. I live in a very hot area and the indicated temp climbs while the engine is off.
Should I replace the temp sensor? Any ideas?

Where did you get that code from????????

Andy,
I got it from the flashing led's after holding the switch down for 4 seconds.

No Andy here , but that;s OK..

Code 2 temp sensor would be an engine management code. Not a DM/CE code.

What I meant to ask is where did you find code 2 to be listed as a temp sensor code??
My info states a code 2 from the DM to be a bad 02 sensor heater circuit fault.

Arthur,
Excuse the "andy".
My mechanic looked it up on his repair CD. Could he be wrong?

Arthur,
What I meant to say was that I got two led flashes and the mechanic said that that meant a problem with the temp sensor.
