How do you replace the speed senor on a 2001 cadillac catera
Just in front of the Cat converter, drivers side.
below the front bumper and behind the fasia on the driver side.
It is built in the throttle body assembly the tps you see on line is not correct
into the hood
Typically in the exhaust manifold just before the head-pipe or at the inlet of the head-pipe.
you not need picture the sensor is next to the oil filter
It is located under the coolant reservoir. You can't just replace the sensor. The whole coolant reservoir must be replace. It's a simply 10 minute job.
Check your crank shaft sensor first.
