Question about 2002 Jeep Grand Cherokee
I have a 2002 Jeep Grand Cherokee Laredo I4.0l Inline 6. My engine oil pressure gauge increases to H whenever I accelerate. It will decrease when I slow down or break but never goes back down to the half marking like it normally should. I'm scheduled for another oil change in about 1 1/2 months. I'm not car repair savvy & I don't have a trusty mechanic. I usually got to Firestone or Pep Boys whenever I have need a repair, but I am curious as to what my problem could be without spending a lot of money just to identify the problem
Hi, I had the same problem, same vehicle (same year), same engine. I bought an oil pressure tester at Harbor freight tools for $ 8. I was trying to figure out, if the pressure is really high, or just the sending unit is defective. The tester after connecting it to my engine was reading correct pressure for this vehicle ( between 25-30 PSI when idelling), which showed that the oil pressure sending unit is defective. At Advanced autopart store they want about $ 47 for the sending unit, so I put the defective one back in place (still reading H). I'm planning to replace it after next pay check :o) Good luck.

It's normal for your oil pressure to increase when u accelerate, and you actually are much better off w/ a high reading rather than a low. Your oil pressure sending unit may be defective, giving u a higher pressure reading than is accurate. The only other explanation I can come up w/ is what weight oil are u using? If your oil change people are putting the wrong viscosity oil (too light) it could cause a high reading on your gauge (unlikely, since u have different shops do the oil change, unless u specify they use the wrong weight oil). I would not worry about it if u r using the proper oil. countrycurt
