Electrical Test (1.6L and 2.2L Turbo Diesel Models)

WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. Move ignition key to the "OFF/LOCK" position and remove key.
  2. Set park brake.
  3. Disconnect the clutch interlock/upstop switch connector.
  4. Using an ohmmeter, check for continuity between terminals 1 & 2 with the upstop switch depressed (clutch pedal at rest). The ohmmeter should show continuity (0 ohms).
  5. Depress the clutch pedal at least 33 mm (1.30 in.) and check for continuity between terminals 1 & 2. There should be no continuity between the terminals (open circuit).
  6. If ohmmeter readings do not fall within these ranges, the switch assembly is defective and should be replaced. If the switch tests OK, wiring is defective. Refer to Wiring Diagrams and repair defective wiring.
