My Oil Lamp Turned On

[fe4snake]

Last night while driving my car, I noticed that my oil lamp had turned on but the oil pressure gage was reading fine. Also, it did not illuminate the MIL. Afterwards I shut off the engine and restarted back up again with the oil lamp light not illuminating.
Has this happen to anyone here before? Could it be that the sensor is starting to malfunction?

The sensor can malfunction. However, i'd start with the obvious; Manually check your oil level.

There are 2 circuits in the sensor; one for the gauge and one for the light. One can go bad while the other still works. Does it light briefly during initial key on?

 

[fe4snake]

Yes it does light up when key is in on position. I did replace the oil pressure gauge sensor that is by the oil filter housing. This sensor is next to it by on the block.

OK. Just checked my factory service manual, as opposed to the CD version Mitchell manual I was looking at earlier, and there are 2 sending units, not a 2 in 1 as I suggested earlier. So yes, one could be bad for sure while the other works fine. But, you said you replaced the gauge sending unit. Was that process related to the light coming on, because, um, makes no sense to do that. Splain!

 

[fe4snake]

Yes, the gauge unit did go bad. So, I did replace it and the warning light never came on due to that. The gauge, was the only thing that was not working. In this case now the gauge is working fine and is reading 55 psi at idle. But, the warning lamp is now turning on eventhough the oil gauge is reading good oil pressure.

Oil pressure sending unit is for the gauge.
Oil pressure switch is for the light. I have found that they will stick from time to time. If you need the switch, I keep a couple of them in stock, MSRP $24.10 less 20% VCA discount.

Thank's Chuck, I'll give you call to get one.

Where is it andhow easy to swap it? Friends 97GTS has the light come on, but the pressure is good and the oil level is perfect

There are actually three sensors; for the gauge, for the ECU, and the open-close switchfor the idiot light. In Gen 1, they are separate while in Gen 2 I think they are all in the same unit.

this reminded me i need a sending unit myself.

you have had issues with this in the past...

Yes your right. I did replaced the sending unit for the pressure gauge last time and this time is the sending unit to the idiot light. I think they where about 4 months from each other.
