Jeep Grand Cherokee Specific OBD II Trouble Codes (DTC)

Diagnose your Jeep problem

This is the list of Jeep Grand Cherokee OBD-2 Diagnostic Trouble Codes (DTC's) that are used by Jeep to diagnose the vehicle problems. Fault codes usually appear after the "Check Engine" light has come on.



The data provided by the OBD-II system can sometimes pinpoint the specific component that has malfunctioned, saving substantial service time and cost. Scanning OBD-II signals can also provide important information when purchasing a used vehicle. Please refer to Jeep Grand Cherokee owners manual first.



This codes are presented for information only. You can always refer to the list of Standard or generic OBD-II DTC.

Prior to replacing parts, check all connectors between the speed control switch and the PCM for moisture Internally the PCM uses the same A/D (analog to digital) converter for TPS voltage as it does for the speed control switch sense. If the v-37 circuit has voltage bleed over from another source, a code of TPS Shorted to voltage may be set in the PCM. The DN model equipped with rear heat option, has an external water pump to circulate coolant to the rear heater. If you find coolant in the bulkhead connector, the likely cause would be a leaking coolant pump. Pump should be replaced if found leaking. If the code sets when the A/C is turned on go right to the bulk head connector and check for moisture. Check for a shorted clock spring causing the speed control 5 volt feed to be shorted to power.

P0441 (M) Evaporative Emission Control System Incorrect Purge Flow Insufficient or excessive vapor flow detected during evaporative emission system operation. If after performing all powertrain test for P0441 with results that appear to be normal/test pass, check for fuel in the purge canister. If there is fuel in the purge canister check ORVR (on-board refueling vapor recovery) system per service manual section 25. If ORVO is working as designed insure that the vehicle owner is not overfilling the fuel tank.
P0442 (M) Evaporative Emission Control System Leak Detected (medium leak) A 0.040 leak has been detected in the evaporative system. (A faulty gas cap may cause this code). Also see TSB 25-001-02A. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.
P0443 (M) Evaporative Emission Control System Purge Control Valve Circuit An open or shorted condition detected in the EVAP purge solenoid control circuit.

P0455 (M) Evaporative Emission Control System Leak Detected (large leak) A large leak has been detected in the evaporative system. See TSB 25-001-02. Also, possible faulty or loose gas cap. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.
P0456 (M) Evaporative Emission Control System Leak Detected (very small leak) "A 0.020 leak has been detected in the evaporative system. See TSB's 25-001-02A, 18-002-03 and 25-004-01. Also, possible faulty or loose gas cap.
(Also see Notes in P0455 above). Does customer regularly commute on a steep grade (down hill grades in excess of 10%? Has the Leak Detection Pump Operation and Diagnosis booklet (Publication No. 81-170-000606) been used to assist in the diagnosis?
Review and if necessary, perform TSB 18-010-02. Be sure to completely read the TSB. The fix for the condition is a PCM replacement, not a reprogramming of the controller. Be sure that there is not any leaks in the system. This TSB applies in a very limited number of cases and usually in mountainous regions. TSB 18-010-02 Is a PCM replacement correct an erroneous MIL illumination for SAE P0456 that sets when driven on steep grades."

This may occur after driving the vehicle in rain or by washing the vehicle. Also if the rear heater water pump is leaking, as on a DN model with rear heat, the C200 could be contaminated with anti-freeze. Once connector is cleaned from antifreeze contamination, review water pump for potential leak and repair as necessary. If there is water intrusion into the connector, dry the connector and repair area that is allowing water into the connector. This area is the source of many speed control complaints. Various fault codes can be set due to contamination of this connector.
