Camshaft Sensor on 92Q?

[LAQ]

So after Ez lube guys messed around with car, i took it to the dealer, got it diagnosed, and they said it is camshaft sensor that's out of whack and told me it will be around 800 plus bucks to fix-- i said damn!!!!!

THis really sucks. HOw can i get away from this?

Have you checked the harness connection? Even JiffyLube would have to go far out of their way to damage the sensor itself. Yanking on a harness is easy.

I believe the CAS problem has been fixed after cleaning up the connectors and putting di-electric grease on them. It has been few weeks and has no problem so far. THANKS AGAIN FOR EVERYONE'S HELP.

One exprience can share with you!

Last weekend, I can not start my car after refueling my car and back to my home. I searched the threads about this problem that most point to fuel pump problem. I use the same philosophy provided by Q45tech to check the wire first. I open the back trunk and disconnect and reconnect the connectors of fuel pump and fuel controller ( I DO checked the connector pins and they are ok, not rusted) . The problem is gone after reconnect them. So far it is ok.

SO, WE CAN/SHOULD CHECK THE WIRE AND CONNECTORS FIRST BECAUSE THE CAR IS GETTING OLD AND CONTACT COULD BE A PROBLEM.

One more issue on my car is idle. The idle is pretty low if the gear moved to Drive/Rev position, about 500-530, after the engine reaches to normal tempreture. At P/N position, the idle is ok, about 700.

Please give a suggestion to find out the reason of this issue.

Thanks,

so i got the car back, and now the check engine light is off again and runs like real q45. what the hell?

i checked the connectors, they look fine. could it have been fixed when dealer guys disconnected and reconnected the contacts?

i'm perplexed with this situation.

Very possible. I remember this happened to someone else on this board. Cleaned the contacts, good as new.

What do you know. It was like 4 threads down.

Yeah, where do you think the quote in my first reply came from?

[Q45tech]

Thats why the CAS generates two different signals from 2 different parts and electronics as a fail safe.

The one proves 360 pulses per cam revolution , the other 1 pulse every 90 degrees......[enough to crank and run the engine somewhat at least up to 2,000 rpm].
