Diagnostic Test Procedure
2000 Jaguar XKR 2D CoupeSECTION Diagnostic Test Procedure
- Disconnect negative battery cable. Disconnect the ECM connector EM81. Disconnect the TPS connector. Measure resistance between ECM harness connector EM81 terminal No. 10 and TPS harness connector terminal No. 3. Is resistance greater than 5 ohms? If yes, repair high resistance between ECM harness connector EM81 terminal No. 10 and TPS harness connector terminal No. 3. If no, go to next step.
- Reconnect negative battery cable. Turn ignition on. Measure voltage between TPS harness connector terminal No. 3 and ground. Is voltage greater than 5 volts? If yes, repair short to high voltage. If no, go to next step.
- Turn ignition off. Measure resistance between TPS harness connector terminal No. 3 and ground. Is resistance less than 10,000 ohms? If yes, repair short to ground. If no, install a new TPS.
