Power supply to intake temp sensor

[Matt twentyV]

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
itself.
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
code.
