P0122 – Throttle/Pedal Position Sensor/Switch A Circuit Low Input
Encountering the P0122 code in your Chery? Here is a complete guide to its causes, symptoms, and solutions.
WHAT DOES CODE P0122 MEAN
The P0122 trouble code indicates a problem with the throttle/pedal position sensor/switch A circuit, specifically that the input signal is lower than expected. This code is often associated with issues related to the sensor, wiring, or circuit corrosion. When diagnosing the P0122 code, it is essential to understand that the throttle position sensor plays a critical role in engine performance, as it provides the engine control module (ECM) with information about the driver’s desired power level.

DIAGNOSTIC STEPS
When diagnosing the P0122 code, start by inspecting the throttle position sensor and its circuit for any signs of damage or corrosion. Verify the sensor’s voltage and resistance readings using a multimeter, and compare them to the manufacturer’s specifications. Check the wiring and connections for any signs of wear or damage. Use a scan tool to monitor the sensor’s signal and verify that it is within the expected range. Consult the workshop manual for specific diagnostic procedures and troubleshooting guidelines for your Chery model.
HOW TO FIX
Fixing the P0122 code typically involves repairing or replacing the faulty component. If the throttle position sensor is faulty, replace it with a new one. If the wiring or circuit is damaged, repair or replace it as needed. Ensure that all connections are clean and secure. In some cases, reprogramming the ECM may be necessary.
IS IT SAFE TO DRIVE WITH THIS CODE
Driving with the P0122 code can be risky, as it may cause the engine to stall or hesitate, leading to a loss of control. Additionally, it may cause damage to other engine components, such as the catalytic converter. It is recommended to address the issue as soon as possible to avoid any potential risks.
ESTIMATED REPAIR COST
The estimated repair cost for the P0122 code can range from $100 to $500, depending on the extent of the damage and the labor costs.
PREVENTIVE MAINTENANCE TIPS
To prevent the P0122 code from occurring, it is essential to regularly inspect and maintain the throttle position sensor and its circuit. Ensure that all connections are clean and secure, and check the sensor’s voltage and resistance readings regularly. Additionally, avoid exposing the sensor to extreme temperatures or moisture.
When working with the Chery P0122 code, it is essential to use a scan tool to monitor the sensor’s signal and verify that it is within the expected range. Additionally, ensure that all connections are clean and secure, and check the sensor’s voltage and resistance readings regularly. In some cases, reprogramming the ECM may be necessary to resolve the issue. With proper diagnosis and repair, the P0122 code can be fixed, and the vehicle can be returned to normal operation.
