Chevrolet Repair: 2006 Chevy SSR, canister purge valve, chevy ssr


Question
QUESTION: Me and you have been talking about my dads 2006 Chevy SSR. I replaced the throttle body in it tuesday night. I took it out tuesday night after I installed it. It took 20 minutes. I also replaced the gasket. This thing ran like a champ when I test drove it tuesday night. I turned it of 5 times and it started all 5 times. I went to start it yesterday it was 91 degrese outside. It would not start it cranked that was it the motor was turning over but would not start. Here are the codes I got p0443 p1516 N/A N/A p0443 p0689. I erased all the codes and it still would not start. The codes kept coming up every time I tried to start it. I erased all the codes and gave up. I went back outside last night it was like 85 degrese and was cool. I put the key in and it started. It had no codes I took it out it ran great. It will not start if it is hot outside never seen a car do this before. I went to autozone and ordered a canister purge valve solenoid for it. It comes in tomorrtow. Any suggestions. Thanks.

ANSWER: HI SEAN,I REMEMBER YOU,,ARE YOU READING THESE CODES FROM A GENERIC CODE READER ??? IF SO CAN YOU GET INTO GM ONLY ???I ASKED THIS BECAUSE IF YOU ARE READING THESE CODES FROM A GENERIC SCAN TOOL AND GENERIC DATA YOU MAY COME UP WITH [ERRONEOUS CODES.]BUT THIS TIME HOWEVER THE CODES YOU GAVE TO ME ARE GOOD GM CODES. PO443,EVAP PURGE CIRCUIT FAULT.PO689,ENGINE CONTROL IGNITION RELAY FEEDBACK CIRCUIT LOW VOLTAGE..PO1516,THROTTLE ANGLE &PEDAL ANGLE ARE NOT CORRESPONDING..DID YOU RELEARN THIS AFTER YOU REPLACED THE THROTTLE BODY ???? I BET YOU DID NOT. I REMEMBER TELLING YOU THIS WITH THE LAST QUESTION YOU ASKED ME...SO THE 443 CODE IS ONLY A EVAP FAULT,,NOT RELATED TO THIS NO START AT ALL. AS FAR AS HAVING A PROBLEM WHEN ENGINE IS WARMED UP AND NOT WHEN COLD,YOU HAVE TO REMEMBER THAT WHEN THIS ENG IS COLD IT WILL BE IN OPEN LOOP AND COMMUNICATION IS SCARCE BETWEEN SENSORS AND PCM.THIS IS MORE THEN LIKELY WHY IT WILL RUN UNTILL IT SHUTS DOWN WHEN HOT AND RESTART WON'T HAPPEN..AFTER ENG WARMS UP IT IS IN WHAT IS CALLED CLOSED LOOP. NOW EVERTHING IS ALIVE AND WELL AND TALKING TO EVERYTHING. THIS COULD EXPLAIN WHEN IT IS WARMS UP THE THROTTLE BODY AND ACCELERATOR PEDAL ARE NOT COMMUNICATING TO ONE ANOTHER ....YOU MUST OF HAD A BAD TIME WITH YOUR CHEVY DEALER IN THE PAST ???? AS FAR IS THE P689 CODE ,THIS IS A RARE CODE,CONDITIONS FOR RUNNING THIS CODE IS THE ECM DETECTS LESS THEN 10 VOLTS ON THE ECM IGN VOLTAGE CIRCUIT FOR 5 SECONDS. LOW BATTERY PERHAPS,CRANKING A LONG TIME PERHAPS ???? I HOPE THIS HELPS YOU SOME..PLEASE RATE THIS ANSWER FOR ME..THANK YOU TOM...

QUESTION: Yeah I cranked the engine a lot. I have never had a good experience with the dealers around here. What I menu was when it is cold outside it will start. If it is hot side it will not start. The dealer told me to install the throttle body and put the connector on it. Then they told me to turn the key for 1 minute but I did it for 3 minutes. They said that's how they program it. Thats exactly what I did. So most likely I will have to take it to the dealer. Is their another way to reprogram it. Is the throttle body still good or do I need to send it back and get a new one. I didn't replace the pedal module. Was I suppose to. Thanks.

Answer
HI SEAN, THE ONLY WAY WE HAVE EVER PROGRAMMED THIS IS WITH THE SCAN TOOL IN THE RELEARN MODE. THE TB SHOULD BE OK. THE PEDAL MODULE SHOULD BE OK AS LONG AS IT COMMUNICATES,WHICH THEY WILL SEE THIS WITH THE SCAN TOOL...LET ME KNOW IF YOU NEED MORE INFO,,TOM
