According to my factory service manual the voltage at the throttle position sensor should vary from about 0.5 volts in the idle position to 5.0 volts in the wide open throttle position.
It is attached to the throttle body exactly opposite the cam/lever with the cable(s) on it.
tps will be located other side ofthrotle to accel cable check for clean connection at tps plug replace tps unless you can test unit dave.cop
To remove the throttle position sensor: 1. Unplug the electrical harness. 2. Remove the bolt that holds the tps in place. 3. Remove the tps. To install a new tps reverse the removal procedure. There is no adjustment given.
NO ajust on tps sensor,. Replace
high voltage at the tps.
get a scanner and check the datastream for the TPS sweep voltage or go to a qualified mechanic for a diagnostic
The throttle position switch (tps) is located on the throttle body.
The TPS needs to b change
on throttle body
Check your TPS TPS = throttle position system
On my 1997 Silverado the TPS is right in the accelerator pedal. Look close at your pedal for the wire and plug in module.
P0121 = TPS Voltage Does Not Agree With MAP sensor signal. That likely means the TPS (throttle position sensor) has gotten dirty inside and is sending out an erratic voltage the computer doesn't like. The usual fix for this is to replace the TPS which is a fairly easy "one-banana" job. The TPS cannot be cleaned when it goes bad, it can only be replaced.
