Fault symptoms


CHECK ENGINE

Misfiring can occur before trouble code is generated.


On-Board Diagnostics

Type of diagnosis:


- Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.


Enable criteria:


- Engine running. Main relay voltage exceeding 10V.


Fault criteria:


- Voltage higher than 2 V for more than 3 s.


Dependents:


- P1135 and P1136.


System reaction to a fault:


- Closed loop is blocked.


OK report:


- P0134 Test 1 and Test 2 performed once and fault criteria not fulfilled. 60 s has expired and closed loop still active. Fault criteria for P0131 or P0132 not fulfilled.


Fault handling: (For more information, see .)


- Type III.


Diagnostic help

Fault diagnosis concerns an electrical fault in connecting leads or in the sensor.

Functions in the diagnostic tool related to the fault:


Diagnostic status for the diagnosis.

Oxygen Sensor Value, unit V.


For more information, see .

Note

The oxygen sensor receives reference oxygen from the surrounding air via the connecting cables. For this reason, electrical contact spray or grease must not be used on the oxygen sensor connector.


Checking the wiring

Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits. Observe the multimeter, diagnostic tool or test lamp during the check.
