Diagnostic help
Fault diagnosis concerns electrical faults in connected leads or in the sensor.
Diagnostic tool functions related to this fault are:
|
•
|
Pressure sensor reading, in kPa. With the engine switched off, this reading should be the same as those for the other two pressure sensors. Permissible variance 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.
