⁽¹⁾	With oxygen sensor heaters, EVAP and without EGR.

⁽²⁾	With California and Federal emissions, oxygen sensors, EVAP, EGR with EGR temperature sensor, and speed limiter.

⁽³⁾	If ECM is encoded with this code, vehicle will exhibit poor driveability, increased fuel consumption, excessive emissions, decreased transmission life and false codes.

⁽⁴⁾	On vehicles equipped with oxygen sensors, if ECM is encoded with this code, the oxygen sensor control, EVAP system and EGR system may not operate.

⁽⁵⁾	Without oxygen sensors, EVAP and EGR.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
