P1121 12 TPS Output Range
Malfunction
2
zConfirm whether the output pin
position of the sensor is correct or short
circuit occurs?
zReplace with a new sensor according to
the part-exchanging process to confirm
whether the error code still exists?
P1122 06 TPS Variation
Malfunction
2
zCheck whether the output pin position
of the sensor is correct or short circuit
occurs?
zIf the check result of step1 is OK and
the error code still exists, then replace
the TPS according to the
part-exchanging process to confirm
whether the error code disappears?
P1168 18 (Fr) O2 Sensor F/B
Malfunction
2
zConfirm the resistance of the sensor
exist open or short circuit?
zConfirm whether the output pin
position of the sensor is correct or open
circuit occurs?(the ECU pin 108)
zIf the check result of above steps is OK
and the error code still exists, then
replace the sensor according to the
part-exchanging process to confirm
whether the error code disappears?
P1169 17 (Fr) O2 Sensor F/B
Malfunction
2
zConfirm whether the resistance of the
sensor exist open or short circuit?
zConfirm whether the output pin
position of the sensor is correct or open
circuit occurs?(the ECU pin 20)
zIf the check result of above steps is OK
and the error code still exists, then
replace the sensor according to the
part-exchanging process to confirm
whether the error code disappears?
zConfirm whether the fuelling system
work normally?
P1560 04 Sensor Power
Circuit Malfunction
2
zConfirm whether the ECU pin 8
outputs 5 V DC?
zConfirm whether the supply voltage of
all sensors is 5 V DC? (the voltage
difference between ECU pin 8 and pin
12)
zIf the check result of step2 is 5 V DC
and the error code still exists, then
replace the ECU according to the
part-exchanging process.
