P2028 Dodge Code - Evaporative Emissions Fuel Vapor Temperature Sensor Circuit Intermittent
Quick Answer
The P2028 diagnostic trouble code for Dodge vehicles indicates an issue with the Evaporative Emissions Fuel Vapor Temperature Sensor Circuit being intermittent. Common causes include Faulty Fuel Vapor Temperature Sensor: The sensor itself may be malfunctioning, leading to intermittent readings and triggering the P2028 code, Damaged Wiring or Connectors: Issues with the wiring or connectors in the sensor circuit can disrupt the flow of data and cause intermittent circuit problems, Evaporative Emissions System Leak: A leak in the evaporative emissions system can also trigger the P2028 code by affecting the sensor's ability to accurately measure fuel vapor temperature. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2028 Dodge Description
The P2028 diagnostic trouble code for Dodge vehicles indicates an issue with the Evaporative Emissions Fuel Vapor Temperature Sensor Circuit being intermittent. The evaporative emissions system plays a crucial role in preventing fuel vapors from escaping into the atmosphere, reducing pollution and maintaining optimal fuel economy. The fuel vapor temperature sensor is responsible for monitoring the temperature of fuel vapors within the system. When this sensor detects an intermittent circuit issue, it means that there may be disruptions in the sensor's ability to accurately measure fuel vapor temperature.
Common Causes of P2028 Dodge
- Faulty Fuel Vapor Temperature Sensor: The sensor itself may be malfunctioning, leading to intermittent readings and triggering the P2028 code.
- Damaged Wiring or Connectors: Issues with the wiring or connectors in the sensor circuit can disrupt the flow of data and cause intermittent circuit problems.
- Evaporative Emissions System Leak: A leak in the evaporative emissions system can also trigger the P2028 code by affecting the sensor's ability to accurately measure fuel vapor temperature.
- Corrosion or Rust: Corrosion or rust in the sensor circuit components can cause poor electrical connectivity and lead to intermittent circuit issues.
- Environmental Factors: Extreme temperatures or exposure to harsh environmental conditions can also impact the performance of the fuel vapor temperature sensor and contribute to the P2028 code.
Symptoms of P2028 Dodge
- Check Engine Light: The most common symptom associated with the P2028 code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A faulty evaporative emissions system can lead to decreased fuel efficiency, as fuel vapors may not be properly contained and utilized.
- Rough Idle: In some cases, the vehicle may experience rough idle or hesitation during acceleration due to issues with the evaporative emissions system.
- Increased Emissions: A malfunctioning fuel vapor temperature sensor can result in increased emissions from the vehicle, potentially causing it to fail emissions tests.
- Fuel Smell: A noticeable fuel smell inside or outside the vehicle may indicate a problem with the evaporative emissions system.
How to Fix P2028 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the root cause of the problem, whether it's a faulty sensor, wiring issue, or system leak.
- Inspect Wiring and Connectors: Check the wiring and connectors in the sensor circuit for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Replace Fuel Vapor Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-approved sensor to ensure accurate temperature readings.
- Repair Evaporative Emissions System: Address any leaks or issues in the evaporative emissions system that may be contributing to the P2028 code.
- Clear Codes and Test Drive: After completing the repairs, clear the trouble codes from the vehicle's system and test drive to ensure that the issue has been resolved.
Cost to Fix P2028 Dodge
The typical repair costs for addressing a P2028 code on a Dodge vehicle can vary depending on the specific cause of the issue and the parts or components that need to be replaced. On average, the repair costs for this type of problem can range from $200 to $500, including parts and labor. However, it's important to note that the actual repair costs may differ based on factors such as the location of the repair shop, the make and model of the vehicle, and the extent of the repairs needed. Additionally, the diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. It's recommended to consult with a trusted mechanic or dealership to get an accurate estimate for the repair.
