OE-Style Throttle Signal Replacement

Hitachi TPS0001 is a throttle position sensor used to report throttle angle to the engine management system. Accurate throttle input is important for fuel delivery, idle control, and drivability, especially on Nissan Altima and Nissan Sentra models where the sensor must match the original connector and mounting style. This part cross-references Nissan OE numbers 22620-4M511 and 22620-9E000 for the same application.

What It Helps Address

• Erratic throttle signal readings
• Hesitation during acceleration
• Unstable idle behavior
• Throttle response concerns
• Check engine light conditions related to throttle position input

Installation Notes

Verify connector count, terminal layout, and two-bolt mounting before installation. The TPS0001 is listed with 6 terminals, male blade terminals, and two connectors, so matching the original sensor configuration is important for proper fitment. Confirm vehicle application by year, make, and model before replacement on Nissan Pathfinder, INFINITI QX4, or other listed vehicles.
