2011 , no jeep stated, they have names, what is it ,
is it in USA> and is it with automatic trans.
in usa there are 5 jeep models, pick on?
is engine gas (petrol or diesel)
my guess that was TPS, P0869
ill now pretend you said, Grand Cherokee, usa.
and i look in the book and it shows.
transmission.
P0869-LINE PRESSURE HIGH you can read the words , in the book (JEEP)
"Theory of Operation
Line pressure is measured by the Line Pressure Sensor (LPS) and regulation is achieved by changing the duty cycle of the Pressure Control Solenoid (PCS) controlled by the Transmission Control System. (5% duty cycle = solenoid off = max line pressure, 62% duty cycle = solenoid on = min line pressure). The Transmission Control System calculates the desired line pressure based on inputs from both the engine and transmission.
The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the desired line pressure calculation. This is called Torque Based Line Pressure. In addition, the line pressure is set to a preset level 827 or 931 kPa (120 or 135 psi) during shifts and in Park and Neutral to ensure consistent shift quality. The desired line pressure is continuously being compared to the actual line pressure. If the actual line pressure is consistently higher than the highest desired line pressure ever used in the current gear, the line pressure high DTC P0869 will set."

means get car serviced.

I have a 2002 yukon xl 1500 slt 5.3.I'm having problems with my abs control module and also a code of p1810.Do u have any suggestions as to what I can do?Help I'm low on cash


Melisssketer,
The P 1810 code is usually the transmission, here are some possible causes;
- Faulty automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch
- TFP Valve Position Switch harness is open or shorted
- TFP Valve Position Switch circuit poor electrical connection
The automatic Transmission Fluid Pressure (TFP) manual valve position switch consists of five pressure switches (two normally-closed and three normally-open) and a Transmission Fluid Temperature (TFT) sensor combined into one unit. The combined unit mounts on the valve body. You could have a problem with any one of these switches. If this is the problem with your car, parts will not be cheap but it can be done without pulling the transmission. I hope this helps, Ray

Po870 code on my Honda


code po870 refers to transmission fluid pressure(TFP) sensor C---circuit malfunction===causes--wiring---poor connection--TFP sensor---ECM/TCM. Check that the wiring and connections are in good condition and all the pins are clean. Replace the sensor and have the transmission control module check out.

Loss of power, transmission issues


code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)
code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again)
code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)
code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734)
code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.
