Laymans terms

This code means that the car's computer is getting a signal from the throttle that's too high. It's like if you were playing a video game and the joystick was stuck, making the character move without you doing anything.

Explanation

The throttle position sensor (TPS) sends a signal to the engine control module (ECM) to indicate the position of the throttle. A 'high' circuit condition indicates that the signal voltage is higher than expected.

Technical description

The P2622 code is triggered when the ECM detects a voltage signal from the throttle position sensor that is above the specified range. This could be due to a short circuit, a faulty sensor, or wiring issues.

Symptoms

• Check Engine Light is on

• Poor acceleration

• Unstable idle

Common Causes

• Faulty throttle position sensor

• Short circuit in the wiring

• Bad ECM

Glossary

Throttle Position Sensor: A sensor that monitors the position of the throttle in an internal combustion engine.

ECM: Engine Control Module, the computer that controls the engine's operations.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the throttle position sensor and its wiring for damage.

• Test the voltage output from the throttle position sensor.

Repair procedures

• Replace the throttle position sensor.

• Repair or replace damaged wiring.

• Replace the ECM if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Screwdriver set

Sensor Issue

User experience recommendations

• Avoid driving aggressively until the issue is fixed.

• Get the vehicle checked by a professional mechanic.

• Do not ignore the Check Engine Light.

Warranty information

Check if the vehicle is still under warranty for powertrain or emissions components.

Historical data

This code has been reported in various vehicles, often caused by sensor failure or wiring issues.

Urgency level

Moderate – It should be addressed soon to avoid further engine performance issues.

Testing conditions

• Engine running

• Throttle fully closed and fully open

Component location

The throttle position sensor is usually located on the throttle body, which is connected to the intake manifold.

FAQs

Q: Can I drive with a P2622 code?
A: It's not recommended as it can lead to poor engine performance and unsafe driving conditions.

Q: How do I reset the Check Engine Light?
A: After repairs, use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes to reset the system.
