Compass. 2005? it was introduced in 2006 but marked 2007 what engine?
2.0 L World I4 (gasoline) 2.0 L VW I4 (turbo diesel) 2.2 L OM651 I4 (turbo diesel) 2.4 L World I4 (gasoline)
P1 means factory only code (jeep) 1616 shows up for 2007 and up. only the official message is. P1616-5V OUTPUT REFERENCE VOLTAGE #1 LOW
the PCM sends +5vdc refr, power to many sensors. if one shorts, the voltage drops and this DTC sets. what we do is measure the voltage. then pull those sensors 1 by one. and find the offending sensor. i cant be more SAVVY then that, no engine stated, so .... no sensors to show you. on one gas engine the PCM C2-pin 41 is 5v out. the throttle body uses that. so does cam sensor and crank Hall sensors. or the wire to them shorting to ground.
get car seviced, any ASE tech can fix this, he has the same drawing im reading now.
