06 VE Engine light, ESP turning its self off.....

[JayBoy3]

I drive a ve sv6 only just got it and recently got a 'check engine' message got the RAA out an the dude plug this thing into it apparently it was a 'idle speed forgotten' or some rubbish error code. he said everything else was fine and not to worry. So that was all sweet once he re set it. Few days later and the ESP is turning itself off and also getting a dealer message. Then after a while it goes away and esc comes back on?? This has happened twice now. Frustrating I have no idea what the go is?? Should I try resetting the battery (will I need codes for the radio, if i do)..... Or take it to the dealer (not sure what they will be able to do aside plug the computer in and tell em every things fine and charge me x amount in the process.

Apparently there was a fault to do with timing chains? Does anyone now the specific codes relevant for that? Or does this sound like a different issue. Please help.

Different issue from chains, chains are p0018 or something

Annoying that its not consistent e.g. went away, came back, rest the comp. stayed away for a week, came back, comes on for 10mins goes off.......... wondering if the whole computer is f--ked.

If it's done quite a few km, might be the throttle position sensor/throttle body. Mine is a high km 2006, and it had error codes P0690, V0415, P0500. I replaced the battery, which was on its last legs, and got further error codes of PO690. I replaced the throttle body (which has the throttle position sensor built into it), and no more error codes. I supect that even if the ESP and traction control are fine, they get turned off by the ECU when it thinks it can't trust the signals from the throttle position sensor.

Make sure your battery is in good condition - if it's not, get an Exide or equivalent "Taxi" or "Police" spec battery for your car - they are higher capacity than the standard spec batteries. Then try cleaning the throttle body, and if you get further throttle body related codes, think about replacing the throttle body. From memory, they're around $450, and you can do it yourself if you can use a screwdriver and a 10mm ring spanner or socket.

Good luck.

Thanks a lot mate, unsure of the specific error codes will take note next time and potentially try both throttle body/battery if they correspond. (cheaper than timing chain)
