Answer
HEY DENNIS,I WILL RUN THESE CODES INTO MY ALL DATA PROGRAM FRI MORNING AND GET BACK WITH YOU ASAP.THANK YOU,TIM.HEY DENNIS,I'M BACK.THE CODE P1596 IS A CRUISE CONTROL ISSUE.THERE IS AN OPEN OR SHORT IN THE SPEED CONTROL VACUUM OR VENT SOLENOID CIRCUITS.,THE P0161 IS A 02 SENSOR HEATER FAILURE(HEATER ELEMENT MALFUNCTION).THE P0551 IS A POWER STEERING PRESSURE SWITCH.THE INPUT SIGNALS TO YOUR PCM ARE INCORRECT AND IT IS SEEING A SIGNAL OF HIGH PRESSURE AT HIGH SPEED. I DIDN'T GET THE %26,THAT'S NOT AN ACTUAL CODE I DON'T THINK. THE AIR BAG SYSTEM HAS ITS OWN MODULE AND MUST BE SCANNED UNDER THE REFERENCE OF AIR BAG MODULE TO RETRIEVE ANY AIR BAG CODES.LOOKS LIKE A BAD 02 SENSOR,POWER STEERING SWITCH,AND A PROBLEM WITH THE CRUISE SOLENOID.LET ME KNOW ON THE AIR BAG CODES AND I WILL TRACK THAT FOR YOU AS WELL. DENNIS,MAKE SURE YOU CHECK ALL WIRING AND CONNECTIONS BEFORE YOU REPLACE ANY OF THIS STUFF?SOMETIMES ALL YOU NEED TO DO IS UNPLUG THEM,THEN PLUG THEM BACK IN AND THEY WORK,SO TRY THAT FIRST OK? I HOPE THIS HELPS OUT,THANKS FOR LISTENING TO ME,TIM.
