6.13 error code: P0118 Engine coolant temperature sensor
circuit voltage is too high
Repair Tip.
The fault has been identified as possibly
having the following problems
1) Short circuit between the circuit
connected to the ECU pin and other
power circuits.
6.14 error code: P0116 engine temperature over range
Repair Tip.
The fault has been identified as possibly
having the following problems
1) There is a break, short to 5v or ground
in the engine temperature sensor.
6.15 error code: P0126 Engine temperature signal stuck
Repair Tip.
The fault has been identified as
possibly having the following
problems
1) As the engine runs, the engine
temperature rise performance is not
consistent with the actual engine
temperature.
6.16 error code: P0122 Throttle position sensor circuit voltage is too
low fault
Repair Tip.
The fault has been identified as possibly having
the following problems
1) ECU pin is shorted to ground.
6.17 error code: P0123 Throttle position sensor circuit voltage is too
high fault
Repair Tip.
The fault has been identified as possibly
having the following problems
1) Short circuit between the circuit
connected to the ECU pin and other
power circuits.
6.18 error code: P0130 Oxygen sensor signal unreasonable fault
Fault cause introduction: The system judges that the oxygen sensor
signal is unreasonable when the following conditions occur The
oxygen sensor signal circuit is coupled with the heating circuit.
Repair Tip.
The fault has been identified as possibly
having the following problems
1) Check whether the oxygen sensor
connector is correct and normal.
2) Check whether the oxygen sensor
signal circuit is coupled with the heating
circuit.
Repair Tip.
Check the following items
1) Measure the voltage connected to the
ECU pin to see if it is normal.
Repair Tip.
Check the following items
1) Measure whether the voltage of the
sensor signal circuit at the ECU pin is
normal.
2) Check whether the temperature sensor
model corresponds to the parts list.
Repair Tip.
1) Check whether the engine temperature
sensor installation position is in place.
2) Whether the ECU PIN pin corresponds.
Repair Tip.
Check the following items
1) Measure the resistance connected to
the ECU pin to ground.
Repair Tip.
Check the following items
1) Measure the voltage connected to the
ECU pin to see if it is normal.
