Maintenance Manual for Chery · Windcloud M7.9.7 EFI System
Failure code: P0107 too low circuit voltage of intake pressure sensor
Step Operation Result Solution
1
Connect scanner and commutator, and then turn
ignition switch to “ON”.
Go to next step
Yes Go to Step 5
2
Check Intake Pressure in data stream to see if it is
around 101kpa (specific value is related to site air
pressure).
No Go to next step
Yes Go to Step 5
3
Unplug intake pressure sensor connector from wire
harness and check the voltage between Pin 3 and
Pin 1 of the connector to see if it is around 5V.
No Go to next step
Yes
Repair or
replace wire
harness
4
Check respectively connections between Pin 17 of
ECU and Pin 1 of sensor connector, Pin 33 of ECU
and Pin 3 of sensor connector, Pin 37 of ECU and
Pin 4 of sensor connector to see if short circuit
occurs.

5
Start engine and idle it. Slowly step down
accelerating pedal to dead position and observe
value of Intake Pressure on scanner, and it does not
vary much; quickly step down accelerating pedal to
dead position, the instant increase of value of Intake
Pressure reaches 90kpa or more.
No Replace sensor
Yes

6
Start engine and idle it. Observe value of Coolant
Temperature, it increases along with coolant
temperature.
No Replace sensor
Failure code: P0118 too high indication of engine coolant temperature
sensor
Step Operation Result Solution
1
Connect scanner and commutator, and then turn
ignition switch to “ON”.
Go to next step
Yes Go to Step 6
2
Check Coolant Temperature in data stream to see if
it is equivalent to engine temperature (specific value
is related to engine temperature at that very
moment)
Note: -40℃ value shown constantly may indicate
open circuit.

3 Unplug coolant temperature sensor connector from
wire harness and check the
