Have you recently encountered the P0462 error code in your Dodge Charger? Don’t worry; you’re not alone. This article will guide you through understanding and resolving this issue p0462 dodge charger , ensuring you get back on the road without any further complications. Let’s dive in!

As a Dodge Charger owner, it’s essential to familiarize yourself with various error codes that may occur. One such code is P0462, which specifically relates to fuel level sensor circuit issues. This error code can cause inaccurate fuel level readings, leading to inconvenience and potential vehicle performance problems. In the following sections, we’ll explore the causes, symptoms, diagnosis, repair methods, and prevention tips for the P0462 error code.

What is P0462?

The p0462 dodge charger error code indicates a problem in the fuel level sensor circuit. This sensor is responsible for measuring the fuel level in your Dodge Charger’s tank and sending the data to the engine control module (ECM). When this circuit malfunctions, it can result in incorrect fuel level readings, which can be frustrating and affect your vehicle’s overall performance.

Several factors can contribute to the occurrence of the p0462 dodge charger error code in your Dodge Charger. Some common causes include:

1. Faulty fuel level sensor: A malfunctioning sensor can send incorrect readings to the ECM, triggering the p0462 dodge charger error code.

2. Wiring issues: Damaged or loose wiring connections can disrupt the communication between the fuel level sensor and the ECM.

3. Corroded connectors: Over time, corrosion can build up on the connectors, leading to poor electrical conductivity and inaccurate readings.

4. Electrical problems: Issues with the ECM or other electrical components can interfere with the fuel level sensor circuit, resulting in the p0462 dodge charger error code.


To identify whether your Dodge Charger is experiencing the P0462 Dodge Charger error code, watch out for the following symptoms:

Inaccurate fuel level readings

The most apparent symptom of the p0462 dodge charger error code is inaccurate fuel level readings on your vehicle’s gauge. The gauge may show full even when the tank is not or vice versa, making it challenging to determine the actual fuel level.

Check Engine Light (CEL) illumination

When the p0462 dodge charger error code is triggered, the Check Engine Light (CEL) on your dashboard may illuminate. This warning light indicates that the ECM has detected a problem in the fuel level sensor circuit.

Erratic fuel gauge

In some instances, the fuel gauge needle may fluctuate rapidly or behave erratically, moving up and down unexpectedly. This erratic behavior is often a sign of a malfunctioning fuel level sensor.

Proper diagnosis is crucial for accurately identifying and resolving the p0462 dodge charger error code. Here are some common methods used by mechanics:

OBD-II scanner

Using an OBD-II scanner, technicians can retrieve the specific error code (P0462) and any accompanying codes stored in the ECM. This step helps narrow down the potential causes and provides a starting point for further investigation.

Visual inspection

Inspecting the wiring, connectors, and sensor for any visible signs of damage or corrosion can help identify issues that may be causing the p0462 dodge charger error code.

Testing the fuel level sensor

Technicians may use multimeters or other specialized tools to test the fuel level sensor’s functionality and determine whether it needs replacement.


Once the p0462 dodge charger error code has been accurately diagnosed, it’s time to proceed with the necessary repairs. Here are the general steps involved in resolving the issue:

Step 1: Disconnect the battery– Before working on any electrical components, it’s crucial to disconnect the battery to avoid any potential risks.

Step 2: Replace the faulty fuel level sensor – If the sensor is determined to be faulty, it needs to be replaced with a new one that matches the specifications of your Dodge Charger.


Step 3: Repair or replace damaged wiring and connectors– In cases where the issue lies with damaged wiring or connectors, these components should be repaired or replaced as necessary.

Step 4: Reconnect the battery and clear error codes – Once the repairs are complete, reconnect the battery and use an OBD-II scanner to clear the error codes stored in the ECM.

Step 5: Test the system– After repairs and error code clearance, test the fuel level sensor and gauge to ensure accurate readings and proper functionality.


Prevention is always better than dealing with error codes after they occur. Here are some preventive measures to minimize the chances of encountering the P0462 error code:

1.Regular maintenance– Adhering to your Dodge Charger’s recommended maintenance schedule can help identify and resolve potential issues before they escalate.

2.Avoid overfilling or running on low fuel – Extreme fuel levels can strain the fuel level sensor and potentially lead to its malfunction. Aim to maintain a moderate fuel level whenever possible.

3.Protect electrical connections– Regularly inspect and clean the connectors associated with the fuel level sensor to prevent corrosion and ensure proper electrical conductivity.


In conclusion, the p0462 dodge charger error code in your Dodge Charger can cause frustration and inconvenience. By understanding its causes, symptoms, diagnosis methods, repair steps, and prevention tips, you can effectively address this issue and prevent it from reoccurring. If you’re unsure or uncomfortable with performing the repairs yourself, consult a qualified mechanic for assistance.

Remember, taking prompt action to address the p0462 dodge charger error code will help ensure a smoother driving experience and prolong the lifespan of your Dodge Charger.
