I am getting code 21, TPS voltage too high?
I removed the TPS, I assume this is on the side of the TBI and the
throttle shaft moves the sensor. Anyway, the resistance readings all change
very smoothly as the sensor potentiometer is turned manually so I dont think
the sensor is bad.
What should I look for do, any help I would be grateful. How does this
sensor interact with any other sensors or is it all by itself in the
5.7 liter V8 350
There is a very very small amount of movement possible. 2 torx screws hold
it on the side of the TBI. I will try this, if the voltage remains too
high, what should be done next?
There are 3 wires on a round plug that run into the sensor.
Does anyone know which wire should I read?
Problem is fixed.
I installed new TPS, code is gone.
If your engine has overheated, the TPS could become damaged. I had to
replace the radiator and heater hose and IMO, the TPS must have gotten too
