Starting just this morning, the oil pressure warning light periodically lit while the gauge, which only ever reads half (or 4, straight up), dropped to 0. Then, after a moment or two, the light went out and the gauge went back to normal. I pulled over, waited about 5 minutes and checked the oil level which was full.

Is it fair to assume I have a failing oil pressure sensor/sender? Is this a common or known issue on X300s?

Is it a time consuming job to replace the sensor (assuming that's what it is)?

Thanks in advance,
Rhett

 

Yup, common thing. Sensor doesn't cost much. There was few threads about it before.

 

Anyone have a link to a replacment unit? A search on LNA5642CA didn't yield much.

Thanks in advance,

How about this #: JLM20791

I just posted the info and TSBs about a week ago on this same topic (different thread).

The 1995 X300 (V) 720001 - 746613 have the pressure transducer.
Subsequent cars were fitted with switches and the INST PACK was reprogrammed to suit.

have a parts car? possible? seller says it has cam chain noise/low/no oil pressure. 140,000 miles any thoughts on purchaseing this car

 

Look for another one.

 

thanks for the advice! Passed on that one . I didn't really want a running car so I wasn't tempted to restore it. It didn't have enough useable parts for me to buy it even for $700
