11. The Steps for Implementation of Failure Diagnosis According to Failure Information Records
11.1 Electronic Throttle Failure Failure codes: P012, P0122, P0123, P022, P0222, P0223, P1336, P154, P1558, P1559, P1564, P1565, P1568, P1579, P1604 No. Operating steps Result Follow up steps 1 Put the ignition switch to “ON”.
Next step Yes Next step 2 Pull out the joint of throttle position sensor on harness; use a multimeter to check if the magnitude of voltage between its 3# and 5# pins is around 12V and if a 5V voltage is present between 6# and 2# pins. No 5 Yes Next step 3 Use a multimeter to check if the resistance values between 1#, 4# and 6# pins of the sensor are between 0.5kΩ and 1.6kΩ. No Replace the sensor Yes Replace the sensor 4 Meanwhile, use a multimeter to check if it is break or short circuit between 1#, 4# and 6# pins of throttle position sensor and ECU38#, 54#, 36#; or, turn blade of the throttle to observe if its resistance value jumps and if the resistance values between 1#, 4# and 6# change accordingly with rotation of throttle. No Replace ECU Yes Repair or replace wire harness 5 Connect an adaptor between ECU and harness, use a multimeter respectively check if it is break or short circuit between 1#, 2#, 6# and 4# pins of the sensor and 10#, 32#, 36# and 54# pins of ECU joint. No Replace ECU |
