P0226 Fault Code

P0226 OBD-II Trouble Code Short Description

Throttle Position Sensor/Switch C Circuit Range/Performance

What does trouble code P0226 mean?

The P0226 fault code is a generic powertrain code that indicates an issue with the throttle pedal position sensor or the throttle body. Specifically, it means that the signal coming from the throttle pedal position sensor is lower than the expected range set by the manufacturer.

The throttle pedal position sensor is an electronic component that measures the position of the throttle pedal and sends a signal to the engine control module (ECM). The ECM then uses this signal to determine the appropriate amount of fuel and air to be delivered to the engine. A malfunctioning sensor can cause the engine to run erratically or stall.

The solution to a P0226 fault code is to first inspect the throttle pedal position sensor and the wiring leading to it. If no issues are found, the problem may lie in the throttle body itself. In either case, the faulty component should be replaced to restore proper operation.

It is important to address a P0226 fault code promptly, as running the engine with a malfunctioning sensor can lead to further damage and potential safety hazards. Regular maintenance and inspections can help prevent these types of issues from occurring.


What causes the P0226 code?

P0226 is a fault code that is commonly associated with electronic throttle control (ETC) systems in cars. The code is triggered when the throttle position sensor (TPS) reports an abnormal amount of voltage to the engine control module (ECM) or powertrain control module (PCM). This can be caused by a number of factors, including:

  1. TPS failure: The TPS is responsible for measuring the throttle position and sending this information to the ECM/PCM. If the TPS fails, it can send incorrect or inconsistent signals, resulting in the P0226 fault code.

  2. Wiring issues: The wiring that connects the TPS to the ECM/PCM can become damaged or corroded, leading to poor signal quality and triggering the P0226 code.

  3. Mechanical issues: Sometimes the throttle plate or linkage can become stuck or damaged, causing the TPS to send erratic signals to the ECM/PCM and triggering the P0226 code.

  4. ECM/PCM failure: In rare cases, the ECM/PCM can malfunction and send incorrect signals to the TPS, causing it to malfunction and triggering the P0226 code.

Overall, the P0226 fault code is a serious issue that can impact the drivability and safety of a vehicle. If you experience this fault code, it is important to have your vehicle inspected by a qualified mechanic to determine the root cause of the issue and prevent further damage or safety risks.

Possible Solutions

How to fix P0226?

The P0226 fault code on cars is related to the throttle position sensor (TPS) circuit performance. This fault code indicates that the TPS is producing voltage signals outside of the acceptable range set by the vehicle's computer. Here are a few steps you can take to fix this fault code:

1. Check the TPS Wiring

The first step is to check the wiring for the TPS. Look for any broken wires, loose connections, or corroded terminals. If any of these issues are present, repair or replace the wiring as necessary.

2. Inspect TPS Sensor

The next step is to inspect the TPS sensor. Look for any signs of damage, wear, or corrosion. Replace the sensor if necessary.

3. Reset the TPS

Resetting the TPS may help clear the P0226 fault code. To do this, turn off the engine and remove the key from the ignition. Disconnect the TPS position sensor connector and turn on the engine. Check the TPS voltage with a multimeter while manually opening and closing the throttle. If the voltage readings are within the acceptable range, reconnect the TPS sensor connector.

4. Check the Throttle Body

If the above steps don't work, it's recommended to check the throttle body. The throttle body may need to be cleaned or replaced if it's causing issues.

5. Seek Professional Help

If the above steps don't work, it's recommended to bring your car to a professional mechanic for further inspection and repairs.

In conclusion, the P0226 fault code can be caused by various issues related to the throttle position sensor. We hope these steps help you fix the code and get your car running smoothly again.
