#5088 of 5134 Cooling System Leak ??
Jul 30, 2012 (11:20 am)
97 Jeep Grand Cherokee 4.ol I6: I gave my kid my old jeep to use at college. He is home for summer and I am using it. I worked on it last summer. Replaced water pump, brakes, etc. and all was OK. I am using it this week and it is consuming about a gallon of antifreeze per day. Nothing looks wet. Not a drop of antifreeze on the floor. Very unusual. I fixed a dozen cooling leaks. Engine runs OK. Nothing conspicuous about the exhaust. If head gasket issue, shouldn't I see or feel something. I have had it since 2000 so I know when it's driving OK. I haven't pressure tested it yet. Radiator or radiator cap? Any input welcome. How should I start troubleshooting?

Hi! My Jeep Grand Cherokee 2003 CRD Diesel Engine No: 1J8G8E8A24Y103891has a hard start for the past 3 weeks. I have realized that when it starts, the diesel mixes with the air. There are bubbles flowing through the pipes. I have cleaned the tank. I have bought new diesel filter. I have replaced most of the seals of the pump in front of the engine. We have been looking through the pipe from the tank to the diesel filter. I cannot see any leakage. . When my car is running, it is smooth and has no problem. The only issue is starting. When we start the engine and it is stationary for a while, the diesel starts flowing backwards. The pipes become empty. PLEASE I need some help. If you have any suggestions what next to try, please write back, Thank you!! Samuel Kayuni, Malawi in Africa.

I's it throwing any codes? We never think our kids are gonna not have some fun with it. 100+ mph runs, a total lack of care, and has 10k on the oil he never checks....
Take the damn thing to the shop before it burns up.

lijeepowner1 did you ever figure out what was wrong with your jeep? I think mine is having similar issues to yours.
#5093 of 5134 Code Po705

I have code PO705 i know it is Neutral Safety Switch problem. Anybody know where is switch located in Jeep Cherokee 2007 . Or maybe can tel me more about this code. Thank you.

I checked the Service Manual for a failure code P0705 but could not find that code listed. I found a code for P0850-PARK/NEUTRAL SWITCH PERFORMANCE.
Theory of Operation
The Park Neutral switch rationality test is enabled only for vehicles equipped with a 4/5 speed automatic transmission. This diagnostic checks if the park/neutral switch is incorrectly stuck in the neutral position during driving conditions by comparing Vehicle Speed, Engine Speed, Throttle Position, and Pressure Ratio to the fail thresholds and by looking at the state of the Park/Neutral Switch. The stuck in drive condition is not explicitly checked as the starter relay does not energize and therefore render the vehicle inoperable.
This code will set if the PCM detects an incorrect Park/Neutral switch state for a given mode of vehicle operation. Two trip fault. Three good trips to turn off the MIL.
TRS (T41) SENSE (P/N SENSE) CIRCUIT OPEN
TRS (T41) SENSE (P/N SENSE) CIRCUIT SHORTED TO GROUND
TRANSMISSION RANGE SENSOR
POWERTRAIN CONTROL MODULE (PCM)
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve body assembly. The solenoid/TRS assembly also contains the Transmission Range Sensor (TRS) and five pressure switches that feed information to the TCM.
Hope this helps.

I replaced the solenoid pack after this code (it was 1 of 3) at Chrysler service.
The code never reappeared after that, but in all honesty they replaced the PCM and the ECU too so who knows. Thank god I had the warranty.
I do know that other than that problem the transmission performed admirably until I sold it.
