Introduction to 18919-AM810 Throttle Position Sensor (TPS)
Drive-by-Wire Electronic Throttle Position Precision
In modern drive-by-wire (DBW) engine management systems, the 18919-AM810 Accelerator Pedal Position Sensor serves as the vital link between driver throttle input and electronic throttle body operation. As the pedal is depressed, internal contact brushes sweep along dual resistance tracks, generating two independent voltage curves (Signal 1 & Signal 2). The engine control module (ECM) continuously monitors both signals for consistency.
When aging or worn sensors develop dead spots or resistance drift, signal correlation fails, triggering immediate check engine illumination and forcing the engine into a protective limp-in / fail-safe mode (limiting RPM to ~2,000–2,500 RPM). Replacing the faulty sensor with our OE-spec 18919-AM810 unit completely restores crisp throttle response and normal vehicle drivability without needing to replace the expensive complete metal pedal assembly.

よくあるご質問
Q1: Is 18919-AM810 the sensor only, or the whole pedal assembly?
A: This product is the standalone 6-pin electronic sensor unit. It allows repair shops and vehicle owners to replace just the failed sensor rather than purchasing the significantly more expensive entire metal pedal assembly (e.g. 18002-AM81D).
Q2: Is 18919-AM810 identical to 18919-6N201 and 18919-VK500?
A: Yes. In the Nissan/Infiniti parts catalog and aftermarket interchange databases, 18919-6N201 そして 18919-VK500 are direct functional equivalents sharing the same 6-pin connector geometry, mounting hole layout, and electrical output characteristics.
Q3: What is the connector configuration?
A: It features a standard 6-pin blade terminal connector housed in high-durability polymer with a secure locking tab to prevent vibration-induced disconnects.
Q4: What is your Minimum Order Quantity (MOQ) and packaging?
A: Standard wholesale MOQ is 10 pieces. Units are individually packaged in protective bubble wrap and neutral inner boxes. Custom color packaging, brand stickers, and laser logo etching are available for volume B2B orders.
