P0202 means that there is a problem in the fuel injector circuit #2. You will need to measure the wiring from the injector to the PCM for continuity and the other side for 12V (with ignition in on. Be aware that the ASD relay (auto shutdown relay) will deenergize after some seconds when the engine is not started and you will loose the 12V. Since you only have one injector code, the 12V is most probably OK. I would swap injector #2 with an other (easy to reach) injector and see if the complaint will follow to the other cylinder. If it does, then the injector is bad and need to be changed. If it doesn't, then there is a good change that the driver in the PCM is bad and the PCM needs to be changed in that case.

SOURCE: 2005 jeep grand cherokee ac blows cold only on drivers side

I agree, these vehicles have a problem with the blend doors and since the accuators hit the door when it opens and closes, it breaks the doors. and it's a huge job to replace them.

SOURCE: Jeep Grand Cherokee Limited P0700 diagnostic problem

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

SOURCE: shift indicator light 1999 Jeep Grand Cherokee

There are two parts to it, a voltage resistor, and the EL panel itself.

You need to remove the console first. There are 2 screws under the front rubber pad, two under the cup holder, two in the bin. Remove those six first, take the storage bin out, then slide the rear cupholder out, remove the two screws under the cup holder, and one in front of it.

There are a total of 6 flat screws, and 3 self tapping screws you have removed.

Put the parking brake on, shift the tranny to N, and the transfer case to the middle position if equipped.

Remove the entire console. Slide the shifter beezel as far up vertically as you can. There are 4 clips you ned to remove to do it.
You will see a blue and black wire running into the back. Follow those wires to the resistor. You will see a transparent EL panel attatched to the resistor by two clips.

Usually, one or both of these clips has come loose, causing the light to work intermittantly. Clip them back on, and turn on the headlights to confirm that the light works correctly now.

Re-install everything in the opposite order.

All 3 codes are point to the o2 sensor
the one you want to replace is on the exaust manifold looks like a spark plug with a wire sticking out of it un plug the sensor and it turns to the left to get off install the new one and plug the new sensor in
Thanks

SOURCE: 1999 Jeep Grand Cherokee - drivers side squib

the squib is the explosive charge inside the drivers airbag. It is not serviceable and is part of the airbag, however, the squib circuit includes the clockspring and wire harness and they are serviceable.
Check out this website. The purpose of this website and company is to help peoplediagnose and repair airbag problems themselves without taking them to thedealer (if possible). It offers all thephotos and data you need to understand your airbag system, read the codes andreset the light. It's a pay site, but itcertainly is worth the money ($14.95 for 1 day full access) There's a place to check if your car is listed on the homepage This is quite a complete website with pictures, descriptionsand factory fault code charts as well as a working demo that shows just howeasy these repairs can be. Although itdoes not give step by step instructions, there is enough information in thepictures and the "how-to" pages that most people can do itthemselves. Lots of insurance companies and body shops use this site forthe information they need to repair your car. Lastly, there's a page in this site that tells you whichcars need a scan tool and which ones can be done without one http://www.airbagsolutions.com http://www.airbagsolutions.com/vehicles_list.aspx http://www.airbagsolutions.com/demo.aspx http://www.airbagsolutions.com/scanlist.aspx

Which codes (OBDI or II) do I use for my 1994 Jeep Grand cherokee laredo 4.0 2wd


before 1996 they use onboard diagnosis system for jeep.

when you turn on key you need to count check engine light blinks.

here are codes taken from internet.

11* No crank reference signal detected during engine cranking.
12* Direct battery input to PCM was disconnected within the last 50 key-on cycles.
13** No difference recognized between the engine MAP reading and the barometric (atmosphereic) pressure reading at start-up
14** MAP sensor input below minimum acceptable voltage.
or
MAP sensor input above maximum acceptable voltage.
15** No vehicle distance (speed) sensor signal detected during road load conditions.
17* Engine coolant temperature remains below normal operating temperatures during vehicle travel (thermostat).
21** Neither rich nor lean condition detected from the oxygen sensor input.
or
Oxygen sensor input voltage maintained above the normal operating range.
22** Engine coolant temperature sensor input above maximum acceptable voltage.
or
Engine coolant temperature sensor input below minimum acceptable voltage.
23** Intake manifold air temperature sensor input above maximum acceptable voltage.
or
Intake manifold air temperature sensor input below minimum acceptable voltage.
24** Throttle position sensor input above maximum acceptable voltage.
or
Throttle position sensor input below minimum acceptable voltage.
25** A shorted condition detected in one or more of the idle air control motor circuits.
27* Injector #1 output driver does not respond properly to the control signal.
or
Injector #2 output driver does not respond properly to the control signal.
or
Injector #3 output driver does not respond properly to the control signal.
or
Injector #4 output driver does not respond properly to the control signal.
or
Injector #5 output driver does not respond properly to the control signal.
or
Injector #6 output driver does not respond properly to the control signal.
33* An open or shorted condition detected in the A/C clutch relay circuit.
34* An open or shorted condition detected in the speed control vacuum or vent solenoid circuits.
or
Speed control switch input below the minimum acceptable voltage.
or
Speed control switch input above the maximum acceptable voltage.
35* An open or shorted condition detected in the radiator fan relay circuit.
41* An open or shorted condition detected in the generator field control circuit.
42* An open or shorted condition detected in the auto shutdown relay circuit.
44* An open or shorted condition exists in the engine coolant temperature sensor circuit or a problem exists in the PCM's battery temperature voltage circuit.
46** Battery voltage sense input above target charging voltage during engine operation.
47** Battery voltage sense input below target charging voltage during engine operation. Also, no significant change detected in battery voltage during active test of generator output.
51** Oxygen sensor signal input indicates lean air/fuel ratio condition during engine operation.
52** Oxygen sensor signal input indicates rich air/fuel ratio condition during engine operation.
53* PCM internal fault condition detected.
54* No fuel sync (camshaft signal) detected during engine cranking.
55* Completion of diagnostic trouble code display on the malfunction indicator lamp (check engine lamp).
62* Unsuccessful attempt to update SRI (service reminder indicator) miles in the PCM EEPROM.
63* Unsuccessful attempt to write to an EEPROM location by the PCM.

* - Check engine lamp will not illuminate at all times if this code was recorded. Cycle ignition key as described and observe code flashed by check engine lamp.

** - Check engine lamp will illuminate during engine operation if this code was recorded.

PCM = Powertrain Control Module (the engine computer)
MAP = Manifold Absolute Pressure (the sensor that measures how hard the engine is sucking air through the intake manifold
EEPROM = Electrically Erasable Programmable Read Only Memory (a type of computer chip used inside the PCM)

P0208 injector problem


make sure injector gets 12 volts from ASD relay. then hook a volt meter from positive side of battery to injector driver circuit, it should fluctuate while trying to start. check fuel injector, should ohm at 12-13 ohms if lower it could be shorted......if the pcm injector driver is bad, the only fix is a new computer. you really need s scanner to properly diagnose this.

My sunroof is stuck open on my 1999 jeep grand cherokee laredo? Would it be a fuse? If so, how do you change it?


Check the fuses under the dash on the drivers side, next to the steering column. There should be a fuse puller on the fuse box door. Also a chart of which fuses at what so you can go to the proper fuse. Good luck, Please let me know if this is the solution to your problem.
