Gain access to PCM. Start engine and allow it to reach normal operating temperature. Using a voltmeter, backprobe between PCM connector "B", terminals No. 6 (Light Green/White wire) and No. 9 (Light Green/Black wire). See THROTTLE POSITION (TP) SENSOR VOLTAGE table.
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.
With voltage measurement equipment still in place, insert 0.14" (3.5 mm) feeler gauge between throttle stop and throttle lever. See Figure. Ensure ISC plunger is not contacting throttle lever screw. Loosen TP sensor screws and rotate back and forth until 0.98-1.02 volts is obtained. Tighten TP sensor screws to 14-21 INCH lbs. (1.6-2.4 N.m). Replace TP sensor if it cannot be adjusted to specification.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
