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

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

⁽³⁾	If ECU 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 ECU is encoded with this code, the oxygen sensor control, EVAP system and EGR system may not operate.

⁽⁵⁾	Without oxygen sensors, EVAP and EGR.
