Throttle position sensor replacement
How Much Does A Subaru Throttle Body Sensor Replacement Cost?
An internal combustion engine requires a mixture of air and fuel to provide the energy for combustion. The air-to-fuel ratio needs to be correct for your Subaru’s engine to run smoothly and to deliver a prompt response to your driving throttle demands.
The amount of throttle being requested by the driver is monitored by a throttle position sensor (TPS) which determines the airflow through the Subaru’s throttle body. The throttle position sensor plays a crucial part in the Subaru’s engine management system and if it fails, the check engine light may appear and you may notice engine misfire and/or poor performance.
The throttle position sensor is usually situated next to the Subaru’s throttle body. In some cases, it connects with the butterfly spindle to monitor the throttle position. However, on ‘drive-by-wire’ or electronic throttle control (ETC) systems it can also control the throttle position. It controls the rate and volume of airflow into the engine.
Anytime the air/fuel mixture might be incorrect on a Subaru it is a cause for concern and the problem should be rectified as soon as possible. There is the chance of engine damage if this issue is left for too long and driving an unhappy Subaru is never a relaxing drive.
