When dealing with the Chrysler P0339 Code, it is important to understand the underlying cause and potential solutions. The Chrysler P0339 code is a diagnostic trouble code, indicating a malfunction in the crankshaft position sensor, or CKP. The CKP is a key component of the powertrain control module (PCM) and is used to identify the engine timing and firing order. With this code, the PCM fails to recognize the pattern of the CKP signal and the engine is unable to synchronize. This article will provide an overview of the common causes and potential solutions for the Chrysler P0339 code.
Causes and Solutions for Chrysler P0339 Code
| Causes | Solutions |
|---|---|
| 5-volt supply circuit shorted to voltage | Check the wiring and replace the faulty voltage supply circuit |
| 5-volt supply circuit shorted to ground | Check the wiring and replace the faulty ground circuit |
| CKP signal circuit shorted to voltage | Check the wiring and replace the faulty voltage supply circuit |
| CKP signal circuit shorted to ground | Check the wiring and replace the faulty ground circuit |
| Target wheel/pulse ring bent/broken/missing teeth/excessive runout | Replace the target wheel/pulse ring |
| Crankshaft position sensor | Replace the faulty crankshaft position sensor |
5-Volt Supply Circuit
The 5-volt supply circuit is a key component of the powertrain control module (PCM). It is used to provide power to the crankshaft position sensor (CKP). If the 5-volt supply circuit is shorted to voltage or ground, the PCM will not be able to recognize the CKP signal. This will result in the PCM emitting the Chrysler P0339 code. To resolve this issue, the wiring should be inspected and the faulty voltage supply circuit or ground circuit should be replaced.
Target Wheel/Pulse Ring
The target wheel or pulse ring is a key component of the crankshaft position sensor. It is used to identify the engine timing and firing order. If the target wheel or pulse ring is bent, broken, missing teeth, or has excessive runout, the PCM will fail to recognize the pattern of the CKP signal. This will result in the PCM emitting the Chrysler P0339 code. To resolve this issue, the faulty target wheel or pulse ring should be replaced.
Crankshaft Position Sensor
The crankshaft position sensor is responsible for providing the PCM with the information it needs to identify the engine timing and firing order. If the crankshaft position sensor is faulty, the PCM will fail to recognize the pattern of the CKP signal. This will result in the PCM emitting the Chrysler P0339 code. To resolve this issue, the faulty crankshaft position sensor should be replaced.
Conclusion: Diagnosing and Resolving Chrysler P0339 Code
The Chrysler P0339 code is a diagnostic trouble code, indicating a malfunction in the crankshaft position sensor. Common causes of the Chrysler P0339 code include a faulty 5-volt supply circuit, a faulty target wheel or pulse ring, and a faulty crankshaft position sensor. To diagnose and resolve the Chrysler P0339 code, the wiring should be inspected, the faulty voltage supply circuit or ground circuit should be replaced, the target wheel or pulse ring should be replaced, and the crankshaft position sensor should be replaced. If the problem persists, professional assistance should be sought to ensure the issue is properly identified and resolved. Using these solutions, the Chrysler P0339 code can be easily diagnosed and resolved.
