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
S/N Operation Test Results Actions
1
Connect the diagnostic instrument and adapter, and turn the
ignition switch to ON.
Next step
Yes Diagnosis help
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?
No Next step
Yes
Repair or replace
harness
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.
No Next step
Yes
Check and repair
as per diagnosis
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.
No Diagnosis help
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.)

3
Check for short to power supply 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.
