Power supply to intake temp sensor

Are you getting an error code for the sensor?
I recently traced an error code to a broken solder/
weld where the wire leads attach to the sensor.
Exactly as described by SJM. The contact was
intermittent so the first time I checked with a meter
it ohmed good. Need to wiggle the sensor wire tail
a bit to insure it has good integrity. The sensor
is just 2-wire, it is powered and sensed by the ECU
You can and should ohm out the sensor connections
at the ECU connector. SJM has a good writeup on
this, and Bentley also describes the procedure, just
find the section for troubleshooting the sensor error
