• Code meanings can vary with vehicle, model year, engine
type and options.
• If a code number has more than one definition listed, note
that only one definition applies to your vehicle. Consult
service manual to get the specific definition for your vehicle.
• Each code definition includes a list of possible causes for
the code.
• Follow vehicle service manual procedures to find the cause
of the code.
1) Visual inspections are important!
2) Problems with wiring and connectors are common,
especially for intermittent faults.
3) Mechanical problems (vacuum leaks, binding or sticking
linkages, etc.) can make a good sensor send an incorrect
signal to the computer. This can cause a Trouble Code.
4) Incorrect information from a sensor may cause the computer
to control the engine in the wrong way. Faulty engine
operation might even make the computer show a different
good sensor as being bad!
