12 - Diagnostic Mode


little lost here...

read below..

Everyone has that code. Please read Techinfo. It'* confirming you are in communication with the PCM.

ya i got it... needed to wait a little bit longer...


throwing code 31, 41 and 67.... whats 67?

oh ya btw this is a 91 riviera

you sure it said 67? 65 is tops IIRC and thats an EGR thing. Check again.

As far as 31 and 41

31 - neutral safety switch
41 - cam sensor circuit

yep i double checked it... its code 67...
ill wait and see if anyoneone else has any input on this situation...

also how much of a pita is the cam position sensor to change?? the part is only 18 bucks... but the garage said about 100$ labor... screw that... (well thats what he said) so it loks like ill be doing the work... AHHHHHHHHHHHHHHHHHH lol

Got a 10mm socket, a 6" extension, and a ratchet? It'* right above your water pump in the timing chain cover. Unless of course, the magnet is gone.

Remove the sensor and have someone crank the engine around until you can see the magent (or the hole where it should be) in your timing gear.

Google is your friend. Did you try to search? Got it on the first attempt (Some GM badged vehicles differ in code definitions, especially Buicks):

My book only goes to code 65.NO 67.Maybe its a Riviera thing

Did you read my reply above about Buick codes?

Try again.

hmmm well i just got home.. quite drunk... havent tryed anything.. ill get on it in the morning... ill try to find a riviera forum to see if maybe they have a code 67... or even the 92 + 67 code.. idk.. anything will help... thanks all..
