2.14. Solar term door position sensor circuit for the power supply circuit (fault code P0123)
Serial
number Operation steps Test
results Next step
1 Connect the diagnosis instrument, the
ignition switch is in the "ON" Next step
Yes Next step 2 The observation data stream of "solar term
door is opening", value is between 4 $~10%
(numerical and models have different).
No To step 5
Yes Next step 3 Slow down on the accelerator to the fully
open, the observation data stream of "solar
term door is opening" think, numerical with
the throttle opening increases to about
85~95% (specific numerical models are
different, and in).
No To step 5
Yes Replace the sensor 4 Repeat step 3, the observation data stream
of "solar term door is opening", whether the
existence of value changes in the process of
change.
No Next step
Yes Repair or replace the wire harness 5 Solar term door shifting joint position
sensor wire harness between ECU, check
X1_45#, X1_38#, X1_32#, a#, b# dB and
sensor connector, pin, c# whether the circuit
breaker short-circuit or short circuit of
power supply.
No Next step
Yes Replace the sensor 6 Using a multimeter to check voltage a# and
b# pins of the joint between the value is
about 5V

2.15. The oxygen sensor circuit fault (fault code P0130)
Serial
number Operation steps Test
results Next step
1 Connect the diagnosis instrument, the
ignition switch is in the "ON” Next step
Yes Diagnostic procedures 2 Start the engine, idle running to the
coolant temperature reach normal values,
observe diagnosis instrument monk
"oxygen sensor voltage" items to pay
changes, the display values should lose
uncle is in the range of 100Ma~900mA
No Next step
Yes Repair or replace the wire harness 3 Check the ECU X1 -- 43# X1_59# pins
respectively in sensor connector 3# (with
the oxygen sensor grey connection line
between pins) line is faulty.
No Next step
Yes Maintenance according to the
diagnosis 4 Exhaust system blocking
Fuel injector is leaking
Fuel pressure is too large
Valve clearance is too small.
