3. Shock sensor (see Table 1-5) Table 1-5 4. Intake manifold absolute pressure temperature sensor (see Table 1-6) Table 1-6 39 Diagnostic Trouble Code (DTC) Trouble Location or Type P0325 Shock sensor 1 circuit trouble S/N Operation Test Results Actions 1 Turn off the ignition switch, and stop the engine. Next step 2 Disconnect the shock sensor from the harness. Measure the resistance between pin (1) and pin (2) with a multimeter. Is the resistance greater than 1MΩ Yes Next step No Renew sensor 3 Gently knock around the shock sensor with a small hammer. Check for AC signal output between pin (1) and pin (2) with a multimeter.
Yes Next step No Replace sensor 4 Turn on the ignition switch, and do not start the engine. Next step 5 Connect an adapter between the ECU and the harness. Check for open or short circuit between pin J1-05, J1-69 of the ECU and the pin (1), (2) of the sensor with a multimeter. Yes Repair or replace harness No Replace ECU Diagnostic Trouble Code (DTC) Trouble Location or Type P0107 Intake manifold absolute pressure/atmospheric pressure circuit input low P0108 Intake manifold absolute pressure/atmospheric pressure circuit input high S/N Operation Test Results Actions 1 Ignition switch in position ON.
Next step 2 Disconnect the intake manifold absolute pressure/intake air temperature sensor from the harness. Measure the voltage between pin (1) and pin (3) with a multimeter. Is the voltage about 5V? Yes 4 No Next step 3 Connect an adapter between the ECU and the harness. Check for open or short circuit between pin J1-21, J1-27, J1-42 of the ECU and the pin (1), (3), (4) of the sensor with a multimeter. Yes Repair or replace harness No Next step 4 Turn on the ignition switch, and do not start the engine. Next step 5 In neutral position, start the engine, and keep idle speed. Step on the accelerator.
Through the adapter, measure the voltage between pin (4) and pin (1) with a multimeter, namely between pin J1-42 and pin J1-21 of the ECU. Does the voltage gradually increase to 4V? Yes Replace ECU No Replace ECU Replace sensor
