2.12. The coolant temperature sensor circuit discontinuity (fault code P0119)
Serial
number Operation steps Test
results Next step
1 Connect the diagnosis instrument, the ignition
switch is in the "ON" Next step
Yes To step 6 2 The observed data stream "coolant temperature",
and whether the engine temperature quite (specific
figures and then the engine temperature related).
Note: if the display value often is constant, that
there may be circuit breaker failure.
No Next step
Yes Next step 3 Dial the connector for coolant temperature sensor
wire harness, electrical multimeter check sensor a#
and c# pins of value is commensurate with its
temperature (with specific reference to the relevant
part of the repair manual).
No Replace the sensor
Yes To step 6 4 Dial the connector for coolant temperature sensor
wire harness with a multimeter to check voltage,
the joint a# and c# pins of about 5V.
No Next step
Yes Repair or replace the wire
harness 5 Check the ECU X1_31#, X1_73# pin, respectively
in the line between the sensor connector a#, pin is
open circuit c#.
No Next step
Yes Diagnostic aid 6 Start the engine, idle running. Observation of the
road "Party member on the coolant temperature"
value changes, the display values should be
increased after the engine coolant temperature and
elevated.
No Replace the sensor
2.13. Solar term door position sensor circuit shorted to ground (fault code P0122)
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", whether the data with the throttle opening
increases to about 85~95% (specific data and
models are different)
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 Dial the joints of I solar term valve position sensor
wire harness, check the ECU X1_45#, X1_38#,
X1_32# pin connected circuit between a#, a#, c# pin
on the sensor circuit breaker or whether,
respectively on the power circuit.
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.
No Diagnostic aid
