(1) Not every Chrysler test has an associated P code.
(2) For an Engine Is Cold Too Long" trouble code, the engine does not warm to 176°F while driving for 20 minutes after start. Check thermostat. For an "Internal Controller Failure" trouble code, replace PCM and go to VER-2A: ROAD TEST VERIFICATION  . For a "PCM Failure SPI Communications" trouble code, replace the PCM and go to VER-2A: ROAD TEST VERIFICATION  .
