If you're referring to the Temp. sensor for the temp. gauge in the cluster (probably not), it's also on top of the intake, the next-closest sensor to the firewall.

OK, can anyone elaborate on how to actually test it, i.e. how many ohms over which terminals, etc.? My 300E has been having some issues lately and I would like to rule this sensor out.

Thanks.
