What does this fault code mean?

The control module monitors the internal reference voltage for the sensors. The code is set when a reference voltage in any circuit reads too high, too low or is absent. The fault may lie in a short-circuited wire, a damaged sensor or the control module itself.

Possible causes

Voltage wire to the sensor short-circuited to ground
Voltage wire to the sensor short-circuited to voltage
Damaged sensor
Damaged engine control module

What you can do

1Read and clear the fault code, and test-drive to see whether it returns
2Check the fuses for the sensor supply in the owner's manual
3Look at the connectors and wiring to the sensors for loose contacts, oxidation and chafing
4Use a multimeter to check that the wiring to the sensors has no contact with ground (the body) or voltage, with the connectors disconnected
5If the fault remains after these checks, have a workshop check the sensors and the control module. For a permanent fault the control module may need replacing, which a workshop does
