The DTC 24 indicates the TPS is either too high or too low. Obtaining the codes with a scan tool will narrow it down to exactly which it is. DTC 12 indicates battery input to the Powertrain Control Module (PCM) was disconnected during the last 50 key starts. So it would seem that you tried to clear the code by disconnecting the battery.The TPS supplies the PCM and Transmission Control Module (TCM) with a signal for proper operation. If the signal is missing or bad, then it is very possible the transmission will not shift into Overdrive.With the key ON, you should have about 4.5 volts at the orange (or white/black) wire at the TPS connector. If not, you have a problem with the PCM or the wire going from the PCM to the TPS.If it's good then check voltage at the orange/dark blue wire. Voltage should go from 0 to 5.0 in a smooth and steady manner as you open the throttle. If it doesn't, you have a bad TPS. Then check the TPS ground at the brown/yellow wire and make sure the ground is good. If not, repair the ground wire as required.I would recommend using an analog (needle type) voltmeter to do these tests. A digital meter is too slow to properly see the voltage rise.We need to try and get codes out of the Transmission Control Module (TCM). The lamp in the Overdrive OFF switch is used to signal the various flash codes. To view flash codes, proceed as follows:
Turn ignition key ON-OFF-ON-OFF-ON finally leaving the key in the ON position. Leave the Overdrive OFF Switch in the normal overdrive (ON) position.Immediately begin counting the number of flashes displayed by the Overdrive OFF Switch indicator lamp.
Flash codes will correspond to Powertrain Control Module codes in duration and spacing.
A code 55 identifies the end of flash code transmission. And the possible codes are:
11 No Engine Speed Sensor Signal-12 No Output Shaft Sensor Signal-13 No Vehicle Speed Sensor Signal
14 Governor Pressure Sensor Signal-15 Throttle Position Signal-16 Transmission Temperature Sensor
17 Overdrive Off Switch Circuit-18 System Voltage Out of Limits-19 Standby Voltage Out of Limits
21 Governor Pressure Solenoid Circuit-22 3-4 Solenoid Circuit-23 Torque Converter Clutch Circuit
24 Overdrive Off Lamp Circuit-25 EEPROM Checksum Error
26 Governor Pressure Sensor Offset Drift-55 End of Message
If you still get no codes, then we have to explore a mechanical problem inside the transmission. Possibly the overdrive solenoid not venting or a lower valve body malfunction.
Instead of getting dtc codes from the display of jeep.Get the actual codes detected before going for any part replacement.
If the problem repeats again n again then its advisable to get car scanned at diagnosis center to get error codes, At diagnosis center you will receive the error code.As per the error code it will detect the exact faulty part in the car due to which the problem is occurring.For more help :--- at www.autozone.com its absolutely free to get car scanned.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

Were those codes retrieved from the OBD-II system using a scanner?

    no by tha key and me !



  • Zaraki Jul 19, 2010

    Those are not valid Chrysler/Jeep DTC (Data Trouble Codes), and the OBD-II systen will not flash the DTC's through the MIL ("Malfunction Indicator Light" or better know as the "check engine light") and the good old days of having the MIL flash out a trouble code are long gone. The DTC's in an OBD-II system must be retrieved using a scanner and there is no other way to retrieve those DTC's. Most auto part stores will scan your vehicle for you for free. (remember to write down the DTC(s) correctly)



    Once you have obtained the correct DTC(s) then I will be able to help you find the problem.

    itys nod obd 11 it tha old style obd 1its a cherokee XJ 96 obd 2 is on the grand cherokees and 1year of the cherkees

  • Zaraki Jul 19, 2010

    If it is a 1996 vehicle it is an OBD-II system, and just look out under the hood at the emission label and it will tell you that it is OBD-II equipped.

  • Zaraki Jul 19, 2010

    Also, OBD-I is practically the same as OBD-II, and the DTC's still have to be retrieved using a scanner, and I really do not know what you have been doing but it is not a proper proceedure.

    smoke another 1 bud!!!!!!!! yeah its not right but it can still b done this way i TOOK MY FIRST 2 YEARS AS A APPRENTICE AT GM,and ive built a **** load of these !@#$%ers i figured that some one with a little more exp would b able to tell me wat i needed to replace first

Hi

It seems that the air/fuel ratio might be set up incorrectly. Are you setting the choke on the carp before you start up or are you pressing the gas pedal as soon as you start up? If you are, don't touch the gas pedal in the morning before you start up and see if it still smokes like that and let it warm up a little before giving it any gas.

One of your spark plugs could be fouled out or gapped incorrectly as well. I wouldn't worry about doing anything until you put the Weber on. Then have your guy set it up correctly and if it still does it then check the plugs.

Let us know if you have something more to know else accept the suggestion.
Thank You for contacting Fixya.com
