7. DTC: P0130, Upper Oxygen Sensor Signal Circuit Trouble (see Table 1-20) (Note: If the trouble of P0135 occurs simultaneously, please remove the trouble of P0135 at first, and then go to the following steps.) Table 1-20 8. DTC: P0132, Upper Oxygen Sensor Circuit Voltage Too High (see Table 1-21) (Note: If the trouble of P0135 occurs simultaneously, please remove the trouble of P0135 at first, and then go to the following steps.) Table 1-21 49 S/N Operation Test Results Actions 1 Connect the diagnostic instrument and adapter, and turn the ignition switch to ON. Next step 2 Start the engine, and keep idle speed until the coolant reaches normal temperature.
Check the “oxygen sensor voltage” on the diagnostic instrument, and the voltage should change quickly within 100mV~900mV? Yes Diagnosis help No Next step 3 Check for short to ground between pin 36#, 18# of the ECU and pin A# (to the grey connection line of the oxygen sensor), B# (to the black connection line of the oxygen sensor) of the sensor with a multimeter. Yes Repair or replace harness No Next step 4 A. Check the intake air system for serious leakage; B. Check if the fuel injector is blocke C. Check the spark plug for over-sized gap; D. Check the distribution line for overhigh resistance; E. Check the intake valve guide for abrasion.
