Error code P0228 is displayed and the check engine light is on - what does this mean?
DTC P0228 is triggered by the OBD/EOBD system when a problem is detected with the throttle position sensor (TPS) Circuit C High Input. This fault code indicates that the engine control unit has measured too high a voltage at the throttle position sensor circuit C, which can lead to engine performance problems.
What can cause this error code?
- Defective throttle position sensor (TPS)
- Damaged or corroded cable to the throttle position sensor
- Loose or dirty plug connections
- Short circuit in the wiring of the sensor
- Defective engine control unit (ECM/PCM)
- Faulty throttle valve unit
- Interruption in the ground connection
- Overvoltage in the sensor power supply
What symptoms occur in parallel with fault code P0228?
- Engine performance problems: Reduced engine power and poor acceleration
- Irregular idling: Engine runs unevenly or stalls at idling speed
- Starting problems: Difficulty starting the engine
- Increased fuel consumption: Significantly higher consumption than usual
- Jerking when driving: Engine jerks especially when accelerating
- Emergency running program: Vehicle switches to emergency running mode with limited power
How can the problem with error code P0228 be rectified?
- Repairing trouble code P0228 requires a systematic diagnosis and appropriate measures.
- Replace the throttle valve sensor completely, as this is usually the main cause of error code P0228
- Check all cable connections to the throttle sensor and repair or replace damaged cables
- Clean the plug connections on the sensor, treat with contact spray and connect firmly
- Replace the entire throttle valve unit if the sensor is permanently installed
- Have the engine control unit diagnosed and replace if defective
- Check the ground connections of the sensor and repair if corroded or interrupted
- Measure the voltage supply to the throttle valve sensor and eliminate sources of overvoltage
FAQ - Frequently asked questions about DTC P0228
Can I continue driving with error code P0228?
Continuing to drive with error code P0228 is only possible to a limited extent. The vehicle often switches to emergency running mode, which greatly reduces engine performance. An early repair is strongly recommended, as further engine damage can occur.
How much does it cost to repair error code P0228?
The repair costs for DTC P0228 vary depending on the cause. A new throttle valve sensor costs between 50-200 euros, a complete throttle valve unit can cost 200-500 euros. The working time is usually 1-2 hours.
How can I diagnose error code P0228 myself?
You can read out the code P0228 with an OBD scanner. First check all plug connections on the throttle valve sensor for tightness and corrosion. A multimeter helps to measure the voltage at the sensor.
Is error code P0228 more common with certain manufacturers?
EOBD code P0228 occurs particularly frequently in older vehicles, as the throttle valve sensors wear out over time. Vehicles with electronic throttle valves are particularly affected.
Can bad weather trigger fault code P0228?
Moisture can actually cause fault code P0228 if water penetrates the plug connections or corrosion occurs on the contacts. The code often disappears again after cleaning and drying.
How long does it take to repair fault code P0228?
The repair of OBD code P0228 takes between 30 minutes and 2 hours, depending on the cause. Simply replacing the throttle position sensor usually takes 30-60 minutes, while more complex wiring problems require more time.
