This page is for personal, non-commercial use. The throttle position sensor TPS is part of your vehicle's fuel management system, and helps ensure that the correct mixture of air and fuel is delivered to your engine. 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. These data determine precisely how much fuel to inject into the engine at any given moment. If the throttle position sensor and its other sensor partners do their job correctly, your car accelerates , cruises, or coasts smoothly and efficiently, as you expect, while maintaining optimal fuel economy.
Hi, thanks in advance for your help. I have a Ford Escort Sport with around miles on the engine. It runs fine except that on acceleration at lower rpms the car wants to jump a little. Once the rpms come up it goes away. It sort of seems like it's misfiring, but it's more of a random misfire. I've replaced the plugs and wires. Also, the PCV valve housing and hoses were melted so I replaced them.

CAS has received numerous complaints from consumers on passive seatbelts, fires, transmission failures, tie rod breakage, premature tire wear, stalling and costly engine damage. Premature cracks in gaskets on Escorts cause expensive engine repairs and oil leaks. Ford was forced to recall 7,, vehicles, including Escorts, due to an internal short circuit in the ignition switch. Because Ford concealed significant information from NHTSA, the agency mistakenly closed its investigation into other models. A common and expensive defect is peeling paint on models.
