13. MAP SENSOR Turn the ignition off. Connect the C1 PCM harness connector. Ignition on, engine not running. With a scan tool, monitor the MAP Sensor voltage. Connect a jumper wire between the (K1) MAP Signal circuit and the Does the scan tool display MAP voltage from approximately 4.9 Yes >> Replace the MAP Sensor. Perform the POWERTRAIN VERIFICATION TEST. (Refer to No >> Go To 14 NOTE: Remove the jumper wire before continuing. 14. EXCESSIVE RESISTANCE IN THE (K1) MAP SIGNAL CIRCUIT Turn the ignition off. Disconnect the C2 PCM harness connector. CAUTION: Do not probe the PCM harness connectors. Probing the Is the resistance below 5.0 ohms? Yes >> Go To 15 No >> Repair the excessive resistance in the (K1) MAP Signal cir- cuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - 46 ENGINE ELECTRICAL DIAGNOSTICS KJ |
