#90 of 145 2003 Chevy Venture Crank Shaft Postion Sensor.
Oct 19, 2010 (3:47 pm)
Problem..... I have changed both crank shaft position sensors, have had a relearn procedure done, cleared the codes for the sensor errors and have cleaned the wiring connection under the drivers seat under the van.. I still get the error codes and the van will not always start once I get the code (0336). The sensor tells the fuel pump to come on/off, so I am getting no fuel, but only sometimes.
New alternator, fuel filter, battery. Runs perfect when it does run.
I noticed that just as the van gets to operating temp there is a very small but noticeable hick-up (misfire, hesitation) once it reaches that point, but only for a moment.
Any Ideas on what the cause and fix might be?
#91 of 145 2002 HIGH idle problem
Nov 25, 2010 (4:58 am)
HI all< new to this forum and I was hoping that somebody might be able to help me figure out my HIGH Idle problem on my 2002 Chevy Venture. If you start it and leave it in Park it will have an unusually high idle, this seems to be more aparent when its cold,however it still does it when its warm.. I have 122k on it and since I do most of the Maintenance on it , I should be able to fix it with some guidance and suggestions... Thanks

i am having the same problem but only mine was a little worse my moms venture started out with a knock with the engine so pulled the valve cover over the back of the 1 3 5 cylinders and the rocker arms pulled out so i he da coiled them back in next i was an injector then a plenum gasket then a Ign. Control Module(ICM) then Crank Postion Sensor(CPS)then wires then fuel filter An idle air control motor(IAC) then a mass air flow senser(MAS) so i went on alldatapro and looked at TSBs for a long time and looked until i came across something very promising it talks about P0101 which has all the things that i change that or tested but one thing i didnt do was check the Powertrain Control Module(PCM) also know as (ECM)engine Control module i tried ask techs from chevy they of course didn't give me the info and i work a shop and for 8years tech experience but who ever reads this let it be know that the dealers are still a crook of shit cuz the labor on it is only 1.1hrs and the PCM cost 450 dollars it just and easy way to make money now heres what you do go to the junk yard get a PCM from under a easy compartment located above the air box Two screws and a 7.5mm socket to pull the conecters off then take the old one with you and match the same numbers to the old one it should say something like this SERV.NO.12208644 depending on the number and thats your new PCM if you need re programming for those who dont have a subscibtion to a tech service like alldata or michell or something like that Email me valoremingtonyahoo.com i will send it to you

just want to share my experience with a 2002 venture. van would always start cold in the morning like a brand new car. then only sometimes after my wife would take one kid to school, park for 40 minutes then go to take the other kid and it would crank, sound like it starts but does not. then crank forever and would not start. wait 15 minutes then maybe it will start. anyway this went on for months intermittently. no codes at all. read a lot about CRANK position sensor but because of learn procedure I did not mess with it without a code. then finally CAM position code popped up. only $30 for part, pain because it is under the power steering pump but changed it and for last 2 weeks it has been starting perfectly. other issues but they can wait for warmer weather.

Thanks demeop for sharing your experience. So are you saying you changed the Crank Pos Sensor or the Camshaft position sensor? I'm having similar issues with my '99 Olds Silhouette. Both sensors seem to be a pain to change. But I know I have enough seepage from the engine over the years that could have caused the "easy to start cold, but hard to start warm" problem. Thanks.

no problem stevie0040, I did only change CAM position as that req's no learn, only plug and play. only issue was pulling the power steering pump out, no big deal just sucks to do all that for (1) screw on the sensor. anyhow still have some funny starts but at least now it DOES start since I changed it. But only did it after I got a code for it, which this was intermittent for over a year. just over 100k now so I do need to do plugs and wires, just afraid of the back (3) plugs. either way it can wait til spring. have you done yours yet?
#97 of 145 2004 venture with 31,000 miles Unexplained shutting off
May 26, 2011 (3:15 pm)
Hi,in decemeber 2010 i took my 2004 chevey venture to the dealership for an oil change.the advisor told me that my vechicle is due for the 30,000 miles emission service,which prevents the car from rough idling & prevent stalling. i agreed to have it done..the next day my car stalled. i told it back & the drove it around & nothing happend..3 days later it stalled out again..i took it back again..When they drove it around nothing happened..Until this day i still have the same problems..When it starts in the morning i let it warm up,then about 10-15 minutes later it will just shut off.I replace the battery with a die-hard,had the gas filter changed & still the same problem..Took it two another mechanic they drove it around they said the car was running smooth..They gave me a bottle of tune-up to place in the tank when i fuel up again..Did that and a week later while driving, it just shut off.Please help me..Thank You

Code 0336 is crankshaft position system variation not learned. When the system is reprogrammed, the code goes away. Need I say more?
