Throttle Position (TP) Sensor
NOTE:
All testing procedures are performed with engine at normal operating temperature. For further TP sensor diagnosis, see the TESTS W/CODES
article.
With engine off, unplug TP sensor harness connector. Check and record resistance between terminals No. 2 and 3 with throttle fully closed. See Fig 1. Check and record resistance between terminals No. 2 and 4 with throttle fully closed, then with throttle fully open. If readings are not as specified, replace TP sensor. See the TP SENSOR SPECIFICATIONS table.
