oil pressure guage reads high

[doug davis]

99 C2 usa 50k miles:

My car just got back from the dealer where they replaced a right side cam actuator which had failed. Now my oil preassure guage reads above 5 bar at all times, even with the engine is stopped. The only time it reads zero is when the key is off. After a search, I found many posts about the oil pressure guage reading intermittantly or incorrectly due to a faulty sending unit. I did not find one eactly like mine though. I'm wondering if a sending unit failure can cause this, or did they not hook up a wire or somthing when they had the cam actuator out.

Thoughts?

Thanks,

Doug Davis

If it was not that way before then take it back.

Chances are the connection is loose or the sender has gone bad.

Loren,

Thanks. Definatley not that way before the work. It's going back tommorow.

They might have swapped the two wires on the sensor.

There's no keying to those connectors.

The analog one for the gauge vs. the binary on/off switch for low pressure.

Actually the lugs on the oil pressure sensor are two different sizes as are the connectors on the wires. This makes it very hard to switch the wires, it would be very hard to get the small connector on the large lug.

I'll be damned. I made extra sure I put them on the right way around

when I changed mine. Never noticed they were different sizes. If they

were, wasn't much of a difference. ;-)

Thanks.

Update: Dealer said wires were indeed switched. All fine now.

Editorial: Dealer doesn't check the car our very well after doing work, do they.

Yea that kind of stuff drives me crazy. It seems to happen to me all the time.

I must say, however, this dealer has done a pretty nice job for me all in all. The original diagnosis was a cam actuator failure (i forget the code it threw now 1509 i think) which turned out to be an actual ECU failure (according to them). Anyway the whole mess was 4500$ which lucky for me was covered by an extended warentee. They fought with GE capital for me and I didn't have to pay anything. I'll forgive them one little mistake this time (although I have to admit not checking the engine oil pressure after a pretty big engine repair is a bit disturbing).

Over all I've been pretty happy with them, Cherry Hill Imports in case anybody in NJ, USA interested.
