How does the Subaru Outback throttle position sensor work?

An automobile’s Subaru Outback Throttle Position Sensor sends changing amounts of resistance to the butterfly valve in the throttle, which lets it check the valve angle with more accuracy.

Where is the TPS on a Subaru Outback?

The TPS can be seen in the picture. It is mounted on 2 slotted screws so it can be rotated about the throttle position for adjustment. I marked it’s original position with a knife (for accuracy!), and then moved it just a knife-blades clockwise (i.e. so the throttle would have to be a little more closed for the same TPS response).

What are the symptoms of a bad throttle position sensor?

A faulty throttle position sensor sends incorrect information to the ECM resulting in various issues in the engine, its performance, and fuel economy. Below are common symptoms of a faulty TPS. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component. 1) Car Jerks

How does the idle position sensor work on a Subaru?

Anyway, if a car has an idle position sensor, it essentially switches in a seperate fuelling map when you go idle. One problem with this is the transition from idle to “not idle”. Say the idle map is commanding 4 bannanas of fuel, while the the throttle will be letting in however much air its fully closed position allows.

How much does it cost to replace a throttle position sensor?

If you need to have your throttle position sensor replaced, the cost will depend on the type of car you have. But the average cost of this replacement job isn’t that expensive. The parts will cost you between $75 and $130 on average. The labor costs will be anywhere between $60 and $90, depending on the hourly rate of the mechanics.

What does it mean when your car throttles up while driving?

In these cases, the TPS isn’t providing the right input, the onboard computer cannot direct the engine to work properly. When the car accelerates while driving, it usually means the butterfly valve inside the throttle has closed up and pops open suddenly when the driver presses on the accelerator.
