GRRR... you fix one problem and guess what?

[Jexsi]

While blasting down a B road the accelerator pedal just went straight to the carpet?? Car was still running and idling at 1000RPM, how do I get home?? Well I thought let’s try to get home at idle speed, 36 years later I made the 3 miles back home with the longest and angriest queue of cars behind me, of course every one of them reminded me I am a nob as they sped past me.. long story short, the nipple had jumped out of the retainer at the cable end under the footwell, what a lovely job... managed to get it back in but broke 4 ribs as well, quick tip if/when you have to do this which will happen, fasten a couple of ty raps over the slot where the cable goes into the bracket, now it can’t fall out again!!  So start her up and vroom vroom, all fixed, and as I stare momentarily at the oil pressure gauge, which has always worked perfectly, it goes from 3 Barr to Zero and just stops... scared me to death so I cut the engine, restarted it and the oil warning light went out immediately so I don’t think it’s pressure related, just wondered if I may have loosened something while scrambling around under the footwell? Any ideas on how to troubleshoot?

?

I have had to do that cable on my S4 as well. I can't think of anything that is down there that could be related to the oil pressure gauge other than the wiring under the dash. Bit of a stretch to think that you have disturbed that? Worth just trying a new sender?

Thanks Michael and happy new year!! Is the sender east to  get at? I understand the actual  oil flow sender is a nightmare, or are they the same?

Hi Shaun,

The oil pressure sender is easy to access - it is next to the oil filter in filter housing. You'll need to locate the wiring within the instrument loom and check it through to the gauge.  More broken or bruised ribs to look forward to

Thanks Mike... more happiness ahead, are we having fun yet?

Mike, is this the same sender that controls the red oil warning light on the dash? If so then that red light goes out immediately the engine fires up so seems that it is OK??

[Vulcan Grey]

The same sender, but the wiring in the dash is different. 

Sounds like the wires to the red oil pressure warning lamp are good, but the wiring to the oil pressure gauge is loose.

Remove the seat first, to make it easier to work under the dash!

Thanks, will assume the Lotus position at the weekend

Travis, one more question please, so if the red light is working properly as it is, does that mean that it cannot be a fault with the actual sender itself? 

[Vulcan Grey]

sorry, i was wrong before, on the V8 there is a different oil pressure switch and oil pressure transducer.

So you'll have to check the wiring on the oil pressure transducer on the left side of the engine, as well as at the gauge in the dash.

[mike_sekinger]

Correct - they are different on the V8.   The oil pressure switch is sitting in the LHS side of the block - this is what your dash light is working off.
