Sidekick 1.8L

  1. If using scan tool, go to next step. If not using scan tool, gain access to PCM. Start engine and allow it to reach normal operating temperature. On models with manual transmission, backprobe between ground and PCM connector "B", terminal No. 17 (Green wire). On models with automatic transmission, backprobe between ground and PCM connector "D", terminal No. 25 (Green wire). See THROTTLE POSITION (TP) SENSOR VOLTAGE  table. Ensure voltage increases smoothly as throttle opening increases. If voltage is not within specification, go to step 3). If voltage is within specification, system has returned to normal.
  2. Turn ignition off. Connect scan tool. Select Throttle Position parameter. Ensure voltage increases smoothly as throttle opening increases. If voltage is not within specification, go to next step. If voltage is within specification, system has returned to normal.
  3. Ensure engine is at normal operating temperature. With voltage measurement equipment still in place, ensure fast idle plunger and follower are not in contact with each other. Loosen TP sensor screws and rotate back and forth until 0.35-0.65 volt is obtained. Tighten TP sensor screws to 22 INCH lbs. (2.5 N.m). Replace TP sensor if it cannot be adjusted to specification.
