Hello,
I just recently purchased a 2003 Jeep Liberty 4WD with the 3.7, Stock, and auto trans. I have been averaging 10 ish mpg driving around town. Its been on one road trip since it was purchased. That was about a 150mi trip the day it was purchased and brought home. Since then it has seen mostly city driving.
The 150mi trip average according to the VIC was about 23 or so. Not bad. But, shortly after buying it it started blowing the BCM fuse. That problem was resolved, but also reset the MPG average in the VIC.
When I got it it had been throwing 5 (yes 5) DTCs:
P0133 (Bank 1/1 O2 slow Response --- Cleared DTC, Has NOT Returned, or been flagged as "Pending"
P0158 (Bank 2/2 O2 High Voltage) --- Replaced
P0455 (EVAP Large Leak)
P0442 (EVAP Small Leak) -- Cleaned gas cap seal, DTC Went Away... For now.
P0837 (4wd Switch Circuit Range/Performance)--- 4WD operates correctly, this hasn't popped up after DTC clear either.
Other things that are happening:
- Oil Leak (Most likely cause is Valve Covers (specifically the passenger side), according to info on this site.)
-3 ABS DTCs:
-Left wheel sensor
-Right Wheel Sensor
-Pump Low voltage
I am not as concerned about the ABS codes as I am about the mileage, because it *****. I know its a gas guzzler, but 10MPG in a stock 3.7 is ridiculous.
I bought an Actron CP9850A last night, and damn, does that thing have a lot available! It DID report (via mode 1 or 6?? I believe??) "Test 01 $11 LOW". That should be O2 bank 1/1, right? And even though it hasn't lit the MIL it could still be bad??
The wave form graph for 1/1 looked ok.. but that doesnt mean anything either, right? Also, I noticed that my "Absolute throttle position" even with the engine OFF is "12.6".. Is that normal??
Fuel Trim for 1/1 I have also seen as high as 6% positive.
Anyway, like I said... I have a LOT wrong. With that scan tool I can give you guys anything you need. Just let me know what you want to see.
Thanks again!
