Grand Cherokee oil level sending unit???
Just added a second jeep to the drive, a 1993 grand (ZJ??), anyways the only
fault it has is that the oil level sending unit is wonkie, anyone know where I can get info on this thing? wiring diagram? or ??? . Thankies Snow... |
Re: Grand Cherokee oil level sending unit???
Are you sure it is the oil level sensor? There was a service bulletin
on the '93 V8 for this problem. The original fix was to change the level sensor, but it didn't help. The solution was to change the oil level to 5-1/2 qts instead of 5. They also had a modified dipstick showing the new setting, but you could do it with a file on the old one. The sensor for both the V-8 and I-6 is in the side of the oil pan on the passenger side.

Re: Grand Cherokee oil level sending unit???
You still don't know if it is the sensor or the oil level. As I
stated before, filling the oil to the full mark on the dip stick is still TOO LOW for reliable oil level sensor operation. This only apples to the early '93's (like mine.) When you get the low oil message on the VIC, it can be either low oil or a sensor problem. It doesn't distinguish between them. The easy way to check is to add 1/2-quart to the engine after it shows full. That's what the factory wants. Apparently, the oil sensors in the '93 are positioned to the ragged edge of failure, and there is nothing you can do except add more oil. This appears to have been corrected in the later 93's. Here is what the service manual says about the sensor: "The module will test the oil sensor input immediately after ignition ON. If low oil is detected during the test OR the oil level sensor is bad, the VIC will display this message. The engine on the vehicle outline will also be illuminated. Ignition must be OFF for 1 minute before the oil is checked. If the fault is found, the message will stay on until the ignition turns OFF. Unless the ignition has been off for one minute or longer and the oil fault fixed, the fault will appear again on the next ignition ON." There are two TSB's regarding this problem. The first one applies only to version 03 of the Vehicle Information Center (VIC). The one I have is No. 08-22-93. If the VIC displays"Oil Sensor Shorted" while in diagnostics mode, the sensor may actually be open and visa versa. The diagnostics mode is entered by depressing and holding the select and set buttons simultaneously, while turning the ignition switch on. The second TSB, 09-16-92, is the one describing increasing the oil capacity to 5.5 quarts and using a newly calibrated dip stick. This bulletin applies to vehicles built prior to MDH 08-22-XX and equipped with a 5.2L engine and a vehicle information center. ---- On Sat, 7 May 2005 09:06:36 -0400, "Snow" <snowbal@sympatico.ca> wrote: >Yep its oil level sensor, the info centre display says it is...

If the VIC displays"Oil Sensor Shorted" while in diagnostics mode, the sensor may actually be open and visa versa. The diagnostics mode is entered by depressing and holding the select and set buttons simultaneously, while turning the ignition switch on. The second TSB, 09-16-92, is the one describing increasing the oil capacity to 5.5 quarts and using a newly calibrated dip stick. This bulletin applies to vehicles built prior to MDH 08-22-XX and equipped with a 5.2L engine and a vehicle information center. ---- On Sat, 7 May 2005 09:06:36 -0400, "Snow" <snowbal@sympatico.ca> wrote: >Yep its oil level sensor, the info centre display says it is...

Re: Grand Cherokee oil level sending unit???
Thanks ----, I'll try the diagnostic mode for the vic, by looking at the
dipstick it is close to being a 1/2 litre over the full mark, but I'll look again. Snow...
