How is TPS used in a fuel injection system?

The TPS provides the most direct signal to the fuel injection system of what power demands are being made by the engine. The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes.

What happens when a TPS sensor goes bad?

The data provided by TPS is invaluable for proper starting, idling, and easy throttle response. These operations are affected when a bad throttle position sensor feeds erroneous data to the car’s computer. Because of this, the following can occur: 1. Difficulty while changing gears.

How does the throttle position sensor ( TPS ) work?

The basic principle of the throttle position sensor (TPS) is to detect the throttle valve opening angle which is controlled by accelerator pedal. Then the TPS will send this data to the ECU.

Can a bad crankshaft sensor cause the engine to stall?

If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.

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

Can a bad throttle position sensor cause idle surging?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

What’s the difference between MS1 and MS2 idle?

MS1 has a two point curve, while MS2 and later lets you set a more detailed curve of IAC valve versus temperature. Closed loop mode tries to maintain a target idle speed. While not every car needs closed loop idle, it can help compensate for major changes in load.

How to relearn high idle after throttle cleaning?

The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes. Then turn on your a/c with blower in high position for three minutes.

What causes high idle speed on Mercedes Benz?

A fault TPS sensor can confuse the ECU causing the idle to be erratic or “hunting”. High Idle Speed: The TPS may report faulty values causing the engine idle speed to be increased above normal.

Why does my MegaSquirt engine oscillate at idle?

The MS/Extra code variants provide a closed loop feature that allows targeting a specific idle speed. I recommend leaving the closed loop control off until you have the engine idling well at a steady load. Both badly tuned closed loop idle and badly tuned fuel or spark settings can cause an oscillating idle.

What does the TPS do on a Polaris?

When i would be coasting down a hill at about 10 -15 mph the engine brake would start engaging and releasing over and over.
