After fitting my new MAF i cleared all my codes off
Checked them, and i had none just 4 long flashes.
I have now checked them again and im getting
11 Crankshaft position sencor
23 Mass air flow sencor
24 Idle air control sencor

The check engine light does come on when driving quite often, but i am getting no driving problems, ie car idles normal 500-600 rpm when warm
Car runs sweet since fitting the new MAF, which means i have no probs on boost or high revs now

At a guess, could the Crackshaft position sencor be failing, and if so, could it be giving false readings for number 23 and 24 to be showing??

Also what problems could i be getting from a dodgey Crackshaft position sencor??

Could it be related to my oil and filter change i have done recently?

 

hi m8 only if you filled the oil up to much it will overflow and get into sensors

 

Any other sujestions?
I took the sencor off earlier and cleaned it with some break cleaner, ill reset my Codes again and see what happens...

 

Anybody else?

 

check the engine grounds.. often more than one error code indicates the ground is inefficent

 

Ok thanks

 

easy check is to use a jump lead between battery neg and the block

is the car a 99 or 00 classic?

if so I would be inclined to replace the MAF sensor as a precaution.. if it doesn't cue it you have a spare.. they are about £80 from the dealer.

I have just replaced the MAF and yes its a 99 classic
Ill wipe the codes off and connect a jump lead from the battery to the engine, do i have to drive around with this on?

 

Yes but just to make sure only connect the NEGATIVE

 

will do, ill try it this wknd when i bring her out to play
