Jeep Code P0202 is an issue that occurs in most Jeep models and is related to the Powertrain Control Module (PCM). This code indicates that the Fuel Injector 2 Circuit is open, meaning that the PCM is unable to control the fuel injection of the engine. The cause of this issue can be attributed to a number of different things, such as the Automatic Shut Down Relay Output Circuit being open or high resistance, the Fuel Injector 2 Control Circuit being open or high resistance, or a defective Fuel Injector 2 or PCM. In order to prevent this issue from occurring, it is necessary to identify the root cause and take the appropriate actions.
Causes and Solutions for Jeep Code P0202
| Cause | Solution |
|---|---|
| ASD RELAY OUTPUT CIRCUIT OPEN/HIGH RESISTANCE | Check the wiring in the ASD RELAY OUTPUT CIRCUIT and repair/replace any damaged wires. |
| INJECTOR 2 CONTROL CIRCUIT OPEN/HIGH RESISTANCE | Check the wiring in the INJECTOR 2 CONTROL CIRCUIT and repair/replace any damaged wires. |
| FUEL INJECTOR 2 | Replace the faulty Fuel Injector 2. |
| POWERTRAIN CONTROL MODULE (PCM) | Replace the defective PCM. |
Jeep Code P0202 is a common issue that many Jeep owners are likely to encounter. This code indicates that the Fuel Injector 2 Circuit is open, meaning that the Powertrain Control Module (PCM) is unable to control the fuel injection of the engine. The cause of this issue can be attributed to a number of different components, such as the Automatic Shut Down Relay Output Circuit, the Fuel Injector 2 Control Circuit, a faulty Fuel Injector 2, or a defective PCM. To resolve this issue, it is necessary to identify the root cause and take the appropriate actions. Fortunately, there are a few actions that can be taken to address this issue, the most common of which include checking the wiring in the ASD RELAY OUTPUT CIRCUIT and INJECTOR 2 CONTROL CIRCUIT, replacing the faulty Fuel Injector 2, and replacing the defective PCM.
Checking ASD RELAY OUTPUT CIRCUIT and INJECTOR 2 CONTROL CIRCUIT
When Jeep Code P0202 is present, one of the possible causes is a problem with either the ASD RELAY OUTPUT CIRCUIT or the INJECTOR 2 CONTROL CIRCUIT. To resolve this issue, it is necessary to inspect the wiring in both circuits and repair or replace any damaged wires.
Replacing Faulty Fuel Injector 2
Another possible cause of Jeep Code P0202 is a faulty Fuel Injector 2. If this is the case, it is necessary to replace the faulty Fuel Injector 2 with a new one.
Replacing Defective PCM
Finally, if all other causes have been ruled out, it is possible that the issue is caused by a defective PCM. If this is the case, it is necessary to replace the defective PCM with a new one.
Conclusion: Troubleshooting Jeep Code P0202
Jeep Code P0202 is a common issue that many Jeep owners are likely to encounter. This code indicates that the Fuel Injector 2 Circuit is open, meaning that the Powertrain Control Module (PCM) is unable to control the fuel injection of the engine. To troubleshoot this issue, it is necessary to identify the root cause and take the appropriate actions, such as checking the wiring in the ASD RELAY OUTPUT CIRCUIT, replacing the faulty Fuel Injector 2, or replacing the defective PCM. By taking the necessary steps to identify and fix the issue, Jeep owners can ensure their vehicle is running properly and avoid any potential Jeep Code P0202 issues in the future.
