The Dodge Durango is a well-regarded mid-size SUV known for its powerful performance and versatility. However, some owners have reported issues with the Throttle Position Sensor (TPS), a critical component that directly affects the vehicle’s throttle response, acceleration, and overall drivability.
These problems can significantly impact the Durango’s performance and reliability. Let’s explore the common TPS issues and how they affect your vehicle.
1. Erratic Engine Behavior and Stalling
One of the most common issues reported by Dodge Durango owners is erratic engine behavior, including sudden surges, rough idling, and stalling, especially at low speeds or idle.
This problem is often caused by inconsistent signals from the Throttle Position Sensor (TPS) to the engine control module (ECM).
As the TPS wears out over time, it may send incorrect or fluctuating signals, leading to improper air-fuel mixture adjustments. This results in the engine behaving unpredictably, which can be bothersome and potentially dangerous.
Owners of 2011-2014 Dodge Durango models frequently report these stalling issues on forums like DurangoForum and DodgeForum.
Many have found that replacing the TPS resolves the problem, but ignoring the issue can lead to worsening symptoms and more significant engine performance issues.
2. Delayed or Unresponsive Acceleration
Another common issue with the Dodge Durango’s Throttle Position Sensor (TPS) is delayed or unresponsive acceleration. Drivers often notice that their vehicle hesitates or fails to accelerate instantly when they press the gas pedal.
In some cases, there can be a noticeable lag before the vehicle responds, which can be particularly problematic when quick acceleration is needed, such as merging onto highways or overtaking other cars.
This problem usually stems from the TPS failing to send the correct throttle position data to the engine control module (ECM) on time.
The delay in signal transmission, or intermittent operation of the TPS, leads to a sluggish throttle response, especially under heavy acceleration or load.
Owners of Dodge Durango models from 2012-2015 frequently report experiencing hesitation during acceleration on forums like DodgeForum. Diagnostic scans often point to the TPS as the root cause, and replacing it typically restores proper acceleration response.
3. Check Engine Light (CEL) Activation with Specific Trouble Codes
One of the more straightforward indicators of a Throttle Position Sensor (TPS) problem in the Dodge Durango is the Check Engine Light (CEL) activation. When this light comes on, it’s often accompanied by diagnostic trouble codes (DTCs) related to the TPS.
Common codes include P0121, which signals a Throttle Position Sensor/Switch A Circuit Range/Performance Problem, P0122 for a low input signal, and P0123 for a high input signal.
These trouble codes typically point to issues in the electrical circuit associated with the TPS, such as problems in the wiring harness or connector.
Alternatively, a malfunctioning TPS may produce signals outside the expected range, triggering the ECM to log a fault code and illuminate the CEL.
Owners of 2011-2016 Dodge Durango models often report on forums like DurangoForum that TPS-related codes trigger their CEL.
Replacing the TPS generally resolves the issue, although further investigation into wiring or ECM programming may be necessary in some cases.
4. Sudden Loss of Power
A sudden loss of power is a serious issue that many Dodge Durango owners have reported, particularly when accelerating or climbing hills. This problem can create unsafe driving conditions, especially when power is needed most.
This issue is often caused by the TPS sending incorrect signals to the ECM. When these signals are outside the expected range, the ECM may cut power to the engine as a protective measure.
In some cases, the ECM may activate a “limp mode” to protect the engine, drastically reducing power output to prevent damage.
Drivers of 2013-2017 Dodge Durango models frequently report experiencing sudden power loss on forums like DodgeForum, often during critical moments such as overtaking or driving uphill.
The problem is frequently linked to a malfunctioning TPS, and resolving it usually involves replacing the sensor or reprogramming the ECM.
5. Difficulty Shifting Gears (Automatic Transmissions)
Difficulty shifting gears, especially with automatic transmissions, is another common problem associated with the Throttle Position Sensor (TPS) in the Dodge Durango.
Drivers often experience hard or delayed shifts, particularly during acceleration or when the vehicle is under load, affecting both drivability and comfort.
This issue arises because the TPS provides accurate throttle position data to the Transmission Control Module (TCM).
If the TPS malfunctions, it may send incorrect data, causing the transmission to shift improperly. Inconsistent TPS signals can also lead to poor communication between the engine and transmission, resulting in delayed or rough shifts.
Owners of 2012-2015 Dodge Durango models with automatic transmissions frequently report these shifting problems on forums like DodgeForum.
Many have found that replacing the TPS improves or resolves the shifting issues, especially in vehicles with higher mileage or those used in heavy-duty conditions.
6. Reduced Fuel Efficiency
Another issue tied to a faulty Throttle Position Sensor (TPS) in the Dodge Durango is reduced fuel efficiency. Drivers often notice a significant decrease in fuel economy, accompanied by a lack of engine power and increased emissions.
This problem typically occurs because a malfunctioning TPS sends incorrect throttle position data to the Engine Control Module (ECM).
This can lead to the ECM miscalculating the air-fuel mixture, resulting in inefficient combustion and higher fuel consumption.
Also, the ECM may attempt to compensate for inconsistent throttle position readings by enriching the fuel mixture, further reducing fuel efficiency.
Owners of 2011-2016 Dodge Durango models frequently discuss reduced fuel efficiency on forums like DurangoForum, with many noting that fuel economy improves after the TPS is replaced. This issue is particularly noticeable in vehicles driven in stop-and-go traffic or under heavy loads.
Conclusion
Identifying and fixing Throttle Position Sensor (TPS) problems in your Dodge Durango is essential for maintaining smooth engine performance and fuel efficiency.
Recognizing the signs early, such as erratic engine behavior or reduced fuel economy, can prevent more severe issues. Replacing a faulty TPS can restore your vehicle’s reliability and ensure a safer, more enjoyable driving experience.
