WARNING: This page is about a different car, the 1994 Plymouth Laser and 1994 Eagle Talon. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION section before disconnecting battery.
  1. Ensure basic idle speed is set to specification. See the IDLE SPEED SPECIFICATIONSΒ  table under IDLE SPEED. Install Test Harness Set (MB99138) between TPS and TPS connector. See Fig 1 . Connect Digital Volt-Ohmmeter (DVOM) between TPS output terminals No. 2 and 4. Turn ignition on. DO NOTΒ  start engine.
  2. Check TPS voltage. Reading should be .48-.52 volt. Adjust TPS until correct voltage is obtained. Clockwise rotation of TPS increases output voltage. Turn ignition off, and disconnect DVOM. Disconnect negative battery cable for 10 seconds or more to clear any trouble codes.
