P1121 12 TPS Output Range
Malfunction
2
z Confirm whether the output pin
position of the sensor is correct or short
circuit occurs?
z Replace with a new sensor according to
the part-exchanging process to confirm
whether the error code still exists?
P1122 06 TPS Variation
Malfunction
2
z Check whether the output pin position
of the sensor is correct or short circuit
occurs?
z If 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
z Confirm the resistance of the sensor
exist open or short circuit?
z Confirm whether the output pin
position of the sensor is correct or open
circuit occurs?(the ECU pin 108)
z If 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
z Confirm whether the resistance of the
sensor exist open or short circuit?
z Confirm whether the output pin
position of the sensor is correct or open
circuit occurs?(the ECU pin 20)
z If 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?
z Confirm whether the fuelling system
work normally?
P1560 04 Sensor Power
Circuit Malfunction
2
z Confirm whether the ECU pin 8
outputs 5 V DC?
z Confirm whether the supply voltage of
all sensors is 5 V DC? (the voltage
difference between ECU pin 8 and pin
12)
z If 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.
