Hey guys and gals,
I potentially have a great deal on a 2000 Jeep Cherokee but it has one technical issue that has me contemplating the buy.
After about 10 minutes, the oil pressure gauge drops to zero. The seller has replaced the oil pump and the oil pressure sensor switch. The Jeep runs great with no knocking, pinging (other than valve tick), and is in generally great conditions. So, my questions are:
- Is this a common error for this year? If so, what is the fix?
- Is there a pressure sensor probe (like for cooland temp) that senses the oil pressure? If so, could this have gone bad?
- Could the gauge itself be bad?
The seller is willing to let me take it home for a day or so to test drive it for the weekend. If the Jeep is truly getting zero oil pressure, would it not seize after a few minutes of running?
Any advice is much appreciated!!!
Dave
