Pcm Encoding

NOTE: If PCM does not match vehicle application, the following conditions may exist: poor driveability, increased fuel consumption, excessive exhaust emissions, premature transmission wear, storage of non-existent codes in PCM memory and reduced maximum road speed. Heated oxygen sensor control, EVAP control and other functions may also be inoperative.

Enter self-diagnostics. See ENTERING SELF-DIAGNOSTICS . Select function 07, ENCODE CONTROL MODULE. Press appropriate buttons to input appropriate 3-digit code based on vehicle application. See PCM ENCODING APPLICATIONS table. Press "Q" button to enter input.

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

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

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

⁽⁵⁾	Without heated oxygen sensors, EVAP and EGR.
