Fault symptoms


• CHECK ENGINE comes on after two driving cycles.

• Engine speed drops slower than normal when the accelerator is released.


Conditions

The following conditions apply for this DTC:


• Engine running and the voltage is higher than 4.815 V for more than 1 s.


Diagnostic help

Fault diagnosis concerns electrical faults in connecting cables or in the sensor.

Diagnostic tool functions related to this fault are:


• Pressure sensor reading, in kPa.


With the engine switched off, the reading should correspond with those of the other two pressure sensors. Permissible difference is 10 kPa.

See also the description of readings under Menu "Read Values" for more information.

Check the wiring

Note

Jiggle the leads and in-line connectors at various points and in different directions to detect any intermittent breaks or short circuits in the wiring. Observe the multimeter, test lamp or diagnostic tool while doing this.
