This summary uses the existing diagnostic information shown in full below.
Your car has a sensor that tells the engine how much you are pressing the gas pedal. This code means that sensor is not working right.
The throttle position sensors (TPS) A and B are not providing the expected readings to the engine control module (ECM), indicating a range or performance issue.
The P110D code is triggered when the ECM detects a discrepancy in the readings from the throttle position sensors A and B on bank 1. These sensors are responsible for monitoring the position of the throttle plate, which controls the amount of air entering the engine. If the sensors provide inconsistent or out-of-range signals, the ECM cannot accurately control engine performance.
• Check Engine Light is on
• Poor engine performance
• Hesitation or stalling during acceleration
• Faulty throttle position sensor
• Wiring issues or poor connections in the TPS circuit
• ECM malfunction
Throttle Position Sensor (TPS): A sensor that measures the position of the throttle in an internal combustion engine.
ECM: Engine Control Module, the computer that manages engine performance.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors of the throttle position sensors.
• Test the throttle position sensors for proper operation.
• Replace the faulty throttle position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Ford F-150
• Honda Accord
• Regularly inspect and clean throttle body components.
• Ensure wiring and connectors are secure and free of corrosion.
• Perform scheduled maintenance checks on the vehicle's electrical system.
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
Throttle position sensor issues have been a common cause of engine performance problems since the introduction of electronic throttle control systems.
Moderate – the vehicle may still be drivable but could experience performance issues.
Ignoring this issue may lead to increased emissions and reduced fuel efficiency, which could affect compliance with emissions regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The throttle position sensors are located on the throttle body, typically near the intake manifold.
Q: Can I drive with a P110D code?
A: It's not recommended to drive with this code active, as it may cause poor engine performance and increase emissions.
Q: How do I reset the Check Engine Light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes to reset the ECM.
