2.6. Manifold pressure sensor circuit for the power supply circuit (fault code P0108)
Serial
number
Operation steps Test
results Next step
1 Connect the diagnostic instrument, ignition switch is
in the "ON" Next step
Yes To step 5 2 The observation data stream of "pressure". It is
about 101kPa (numerical and pressure).
No Next step
Yes To step 5 3 Dial the joint air inlet pressure sensor on wire
harness, multimeter voltage check the joint 2# and
4# pins between whether the value is about 5V
No Next step
Yes Repair or replace the wire
harness 4 Check the ECU X1_60#, X1_46#, 1_48#
respectively in the line between the sensor
connector for 1#, 2#, 4# pin is broken
No Next step
Yes Diagnostic aid 5 Start the engine, idle running. Slow down on the
accelerator to close to the fully open, observation
instrument monk "pressure" numerical variation
diagnosis, the display value a little change; quick
throttle to close to the fully open, the display values
should be can instantly reach above 90kPa.
No Replace the sensor
2.7. The intake air temperature sensor circuit shorted to ground (fault code P0112
Serial
number
Operation steps Inspec
tion
results Next step
1 Connect the diagnosis instrument, the ignition
switch is in the "ON". Next step
Yes To step 5 2 The observation data stream in the "air
temperature", whether in the intake pipe of
equivalent temperature (numerical and when the
engine temperature). Note: if the display value
often is constant, that there may be line short circuit
fault
No Next step
Yes Next step 3 Dial connection wire harness the intake air
temperature sensor, using a multimeter check
resistance sensor 3# and 4# 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 air intake temperature sensor connector on
wire harness, multimeter voltage check the joint a#
and b# pins between whether the value is about 5V
No Next step
Yes Repair or replace the wire
harness 5 Check the ECU X1_56#, X1_48# between pin are
respectively connected with the sensor connector,
pin 3# 4# whether the circuit breaker.
No Next step
Yes Diagnostic aid 6 Start the engine, idle running. To observe the
diagnostic instrument "air temperature" value
changes, the display values should be increased
along with the engine air inlet temperature
No Replace the sensor
