Good Ol Check Engine Light

[Sage222]

So i was doing some spirited driving list night.. (in actual fact i was seeing what sort of 0-100 times i can do. (Entering the freeway at the on lights officer)

First run was all good. Second i got to the top near the top of 3rd and felt like a fuel or boost cut.. CEL came on.. limp mode engaged.. Just checked the numbers (and cleared them).

Came up with:

P0018 OBD Trouble Code

1 result found

P0018 - Generic Type Powertrain - Fuel and Air Metering - ISO/SAE Controlled Description

Crankshaft Position - Camshaft Position Correlation

Location Bank 2 Sensor A

Anyone got any experience with this.. I havent tried driving it since i have cleared the code.. I am hoping it will just go away. I am thinking i should drop the boost down a bit too.. currently running LPG, with dump and midpipe replaced, break wire cut, bleed valve with factory controller removed running approx 16psi.. (factory guage reading).

I really hope i aint broken it..

You should have dropped in mate, the generic code descriptions are crap. The consult 3 would have explained it better and allowed direct testing of the sensor. At least the limp mode went away and it wasn't the AFM...

If it's the cam sensor I may have one, but try it out, it can only throw another code and go into limp again...

thanks bud it surprisingly drivable in limp mode. just wont give me any boost Ill take it for another spin tonight hopefully its gone if not ill give you a shout

might seem silly or off track but check that you didn't blow off an intercooler hose???

Bugger. Even after clearing the code next start the cel returned. Attempted to drive it to pickup my kid from his grandma's it still was in limp mode though appeared to be driving ok. Filed it up with gas. Then picked up the kid and then it wouldn't start. Kicks over gets ignition tries to get the revs up to idle about a second and a half then stalls.

f**k.

Had to get the kid home so will have to go have a look tomorrow or Saturday.

Will double check the cel and the hoses and connections though it sounding expensive.

Strange that I managed to start it about 6 times and drove it for 40ks before it died. Only difference I can think of is that it's parked on a angle now. Maybe I'll Jack it up and start it. Really painful cause I didn't get it home.it's on the side of the road.

Suggestions most welcome as always.

Timing belt out? Had a few with that code

"its easy on my C34..."

No timing belt.

Sounds like it might be crank and/or cam angle sensors. Wouldn't be too fussed about the air fuel code considering your running gas

hey Scotty what hardware do I need to read the code properly? it did start btw and I got it home just need to work out what's wrong now :-)

[scotty nm35]

You need the consult 3 unit, and I have the software on my laptop. Would you like me to drop around one night? I can bring the cam sensors, I definitely have one, just not sure on the drivers bank sensor.

[Sage222]

Would be f**king awesome mate. Just let me know when :-)

It was the AFM, I installed a new one for him Wednesday night and reset the code. Must be working fine, no calls yet.
