Oil level control module service?
Have any of you had a problem with the oil level indicator telling you that the oil level is low when it really isn't?
I performed the shop manual diagnostics on my '93 SSEi a while ago, and the oil level sensor in the pan measured ok (200 Ohms, if I remember correctly) and the wiring tests passed, but the light still turns on so the diagnostic says to replace the oil level module.
I removed the module and opened its cover, and checked all components except the larger of the 2 ICs, part #79009 or something like that. There were only 2 ICs on the circuit board, and the other one was a common 8-pin opamp if I recall correctly. I replaced the 8-pin chip but the problem remains so it must be a problem with the other chip. All of the resistors, diodes, and transistors tested ok. I can't find any part info for the 79009 chip.
