Was for 2000 jeep cherokee. After oil change old unit was reflecting high oil pressure. Apparently common problem. New pressure switch and all was good again.

I would advise anyone to stay away from this product. Normally, I have had good results with BWD and/or Carquest parts, but this oil pressure switch is an exception. The switch installs easily and works initially, but that is as far as it goes.

The first two worked for about 2 months (maybe 3,000 miles). Suddenly, the oil pressure went from the usual 40 PSI to about 12 and wouldn't go higher at any RPM. I just about panicked the first time since I had just changed the oil and thought maybe the oil pressure was somehow being affected by that.

I had a mechanic check the pressure (which was fine) and put another BWD switch in. Reading was fine again. This one worked for another 2 months then the same thing happened.

I put another BWD switch in and it worked for about an hour before again going to 12 PSI. I took a slow approach to diagnosis repeating each step short of replacement (even removing the adapter that the switch screws into to see if there was debris). Nothing short of replacement fixed anything.

Today, I just put in another BWD switch... pressure reads good.... let's see how long this 4th switch works.

The switch has a lifetime replacement guarantee which Advance Auto has honored, but I really don't want to spend a lifetime replacing something which usually lasts for many, many years.

Best advice... buy one not made by BWD (check first, because this is the manufacturer for most retailers).

Comments about BWD Oil Pressure Switch:

This sensor was installed in a 2000 Wrangler because the original unit had failed and would show 0 to 15 psi. The new sensor installed fine, and it showed 60 psi but then dropped to 15. Mechanical gauge showed 40. Returned and refunded. Buy a MOPAR sensor, it works, and matched the mechanical gauge.

Comments about BWD Oil Pressure Switch:

Went from having problems with the old OEM switch to having more problems with the new one. Replaced it twice, failed both times with it pegging at 0 or 80 PSI.

        Works great but don't last.
        I have replaced it twice in 2 years on a vehicle that gets casual use. The first one went from normal oil pressure to zero in seconds about giving me a heart attack. Thank god I was home at the time.
        The second failure it was reading about half of what the true pressure was.

                      Hi Rich, I'm glad to assist you. The oil pressure switch and the oil pressure sending unit are same. The oil pressure sending unit controls the oil pressure light or gauge depending on what a car is equipped with. Both the BWD Part No. S4191 and the Omix-Ada Part No. 17219.12 oil pressure sending units are exact fit for your 2000 jeep Cherokee 4.0l.

                      A:

                      If your oil pressure is remaining that high, I would suggest having it checked with a manual pressure gauge to see if the reading is accurate. It sounds to me as if you might have a bad oil sending unit. If the oil pressure sending unit is good, check the oil pressure relief valve. It may be stuck closed resulting in high pressure reading.

                      This could be the cause of your issues, but unfortunately we are unable to diagnose what is wrong with your vehicle without being able to be there with your vehicle. We highly recommend taking your vehicle to a reputable shop to have them take a look at it to determine the cause.
