Honda Civic Throttle Position Sensor Problems & Fixes

Glowing Check Engine Light (CEL)

The issue of CEL on your dashboard can happen to a defective TPS. When this sensor becomes damaged, the engine control unit doesn’t get any data from the throttle position. Thus, the system warns you of the CEL and requires immediate action.

How To Fix It

You must diagnose and identify the suspected TPS. So, you need to bring your vehicle to the dealership or a professional auto mechanic to do it. After a diagnosis of the issue, they’ll be able to ensure whether the TPS wants a repair or replacement to fix the issue.

The Engine Stalling

When your vehicle gets a bad TPS, it makes issues with the engine. Stalling the engine is one of the 2005 Honda Civic throttle position sensor problems that happens for a damaged TPS. You must check the TPS to fix the issue if it occurs repeatedly.

How To Fix It

The engine stalling may happen for several reasons, such as faulty TPS and damaged wires/connections. So, it’s crucial to ensure the exact reason for the problem to fix it. Check the wire connections and damaged wires first. If they’re okay, TPS can be the culprit. You can ensure by checking it through a multimeter. Then, repair or replace the TPS as per needed.

Uneven RPM

Getting uneven RPM can be caused by the damaged TPS. It typically happens if the TPS doesn’t transmit a regular signal to the Engine Control Unit (ECU). Thus, it makes irregular motor revolutions.

How To Fix It

First, check all wires that connect the PCM and the TPS. If they’re okay, then check and diagnose the TPS. Replacing the damaged TPS will help you fix the issue.

Bumpy Acceleration

you can experience the 2000 Honda Civic throttle position sensor problems that happen for the TPS failure. The TPS is responsible for transmitting essential signals to the ECU regarding the required fuel quantity to accelerate the engine. When it doesn’t get the correct signal, it misbehaves with its users.

How To Fix It

Test and identify if the TPS is working properly. If not, replace the damaged TPS.

Higher Fuel Consumption

It’s one of the good Honda throttle position sensor symptoms and reasons for the TPS failure. Also, it may occur for wrong TPS calibration. Both reasons lead to higher fuel consumption than regular driving.

How To Fix It

Most probably, the issue is happening to the TPS malfunction or incorrect calibration. You must check and identify the exact reason with the help of a mechanic. It’s possible to determine the fixing process after recognizing the reason.

Irregular Engine Idle

Many reasons may involve irregular engine idling, including loosely connected wires, incorrect TPS calibration, and TPS failure. So, it requires a deep investigation to find out the associated reasons.

How To Fix It

Primarily, you can try to fix it by reconnecting the wires. If it doesn’t work, consult a professional to get the best results.
