P0214 Fault Code
P0214 OBD-II Trouble Code Short Description
Cold Start Injector 2 Malfunction
What does trouble code P0214 mean?
The P0214 fault code is a diagnostic trouble code that indicates a malfunction in the throttle position sensor (TPS) circuit in a car's engine control module (ECM). The TPS is a crucial sensor that helps the ECM determine how much air should be fed into the engine to achieve optimal performance.
When the ECM detects inconsistency in the TPS circuit, it triggers the P0214 fault code and puts the vehicle into a "limp mode" where it runs at reduced power and performance. This is done to protect the engine from damage caused by incorrect air-fuel mixtures.
The solution to this problem usually involves inspecting the TPS connector, wiring, and sensor for any issues or damage. If any components are found to be faulty, they need to be replaced. Once the issue is resolved, the fault code can be reset using a diagnostic tool.
It is important not to ignore a P0214 fault code, as driving a vehicle in limp mode can cause further damage to the engine over time. It is always a good idea to address any issues with the TPS circuit as soon as they become apparent, to ensure the safe and efficient operation of the vehicle.
What are the symptoms of the P0214 code?
The P0214 fault code is primarily associated with diesel engines, specifically those equipped with a high-pressure fuel injection system. Some symptoms commonly related to the P0214 fault code on cars include:
Engine hesitation or stalling: Prolonged hesitation or stalling of the engine upon acceleration or during idle can be an indication of the P0214 fault code.
Reduced power output: The engine may not deliver power as expected, exhibiting a lack of power response or failing to match the driver's inputs.
Rough running engine: If the engine runs unevenly or with noticeable vibration, it may be a symptom of the P0214 fault code.
Hard starting: Difficulty starting the engine may be an indication of the P0214 fault code.
Illuminated or flashing check engine light: This is usually the first sign of a fault code. It is the most common symptom of the P0214 fault code.
If you experience any of these symptoms, it's best to schedule an appointment with a certified mechanic for a proper diagnosis and repair.
What causes the P0214 code?
P0214 is a diagnostic trouble code (DTC) that indicates a problem in the engine management system of a vehicle. Specifically, it relates to a malfunction in the engine overrun cutoff system.
The engine overrun cutoff system is designed to prevent hazardous engine operation. When a driver takes their foot off the accelerator pedal while the engine is still running, the overrun cutoff system closes the throttle valve to stop the engine from over-revving or producing abnormal noises.
If the engine management computer detects that the overrun cutoff solenoid valve control circuit is malfunctioning or not functioning at all, it generates the P0214 fault code. Some possible causes of this fault code include a faulty solenoid valve, a damaged wiring harness, a blown fuse, or a defective engine control module.
To diagnose and repair P0214, it is best to consult with a qualified mechanic or automotive technician with the proper diagnostic tools and experience.
How to fix P0214?
- Perform a visual inspection of all the engine components and wiring for any damage or loose connections.
- Check the engine control module by performing a diagnostic scan using an OBD2 scanner.
- Check the crankshaft position sensor and replace if faulty.
- Check the throttle position sensor and replace if necessary.
- Clean or replace any defective fuel injector.
- Repair or replace faulty wiring in the engine control system.
If none of the above solutions work, it is recommended to take your car to a certified mechanic for further inspection and repair.
What is code P0214?
