I first had this problem a year ago at 500 hours. It was due to low oil. The reason I had low oil is, I had a User Manual I downloaded from online that was for a previous (by only a few months) version of the 1533 that had a 3 cylinder engine that required about half to 2/3ds of the correct quantity of oil. Boy was I mad! Same model, same year, different engine. Sometime during 2015, Mahindra switched to a 4 cylinder engine that takes 7+ Qts. I solved the problem by changing the oil and filter and replacing the oil pressure sensor.
One year and 150 hours later and I'm getting low oil pressure again. I just changed the oil and filter about 20 hours ago. When the light came on, I waited overnight and checked the oil on level ground. Perfectly full and clean. I checked for leaks. None. l checked for smoke. None. I checked the tail pipe itself. Small amount of dry carbon residue.
I think there are only four possible causes
1. the oil pressure sensor is bad (China).
2. The oil pump is clogged or faulty.
3. The engine bearings are worn. (Man! I hope not. Even with low oil, there's only 650 hours on the engine. That seems unlikely. I hope.)
4. There is debris in an oil passage somewhere.
Here's are my questions:
Any opinions out there on which of these causes is most likely? Any troubleshooting tips?
What's the best way to clean debris from the oil passages?
Are there other causes I haven't thought of or ruled out?
