2002 Lancer OZ Rally...

I recently had an oil change and the O2 sensor (upstream/intake) replaced. After 1000 mi. my oil pressure light has sarted to come on when the engine idles. The idle speed is 700+/-100 and I am within that range, as soon as my RPM gets just above 1000 the light goes off. Any suggestions?

    Sorry, I also noticed that this only happens after the engine is warm. The car does not overheat, no strange noise, appears to operate as normal, other than the light.

I had the same problem with my 2003 Lancer OZ. The oil level and pressure were ok. Car was fine with no light when starting. After 10 to 15 mins of driving it would come on when I was stopped. It would go away when I pressed accelerator. Try replacing the Oil Sending Unit. It's about $10 and easy to swap. That was my problem.

90 percent chance no. I would still take the five minutes and drain some from the pan. Won't even have to take the plug all the way out for the little bit.

2002 mitsubishi lancer oz rally troubleshooting p0420


Code p0420 is 'catalyst efficiency below threshold'.

This could be caused by a bad catalytic converter but before dumping a ton of money on that I would suspect the after-cat oxygen sensor is getting lazy and setting the code.

Have the O2 sensors checked and replace if needed before suspecting the catalytic converter.

Good luck.
