Walker Products 200-1271 right throttle position sensor for the 1995-1996 Infiniti Q45 V8 4.5L detects throttle blade position and sends it to the ECM. The ECM uses that signal to control fuel delivery, ignition timing and transmission shifting.
- Tested for signal integrity, temperature resistance and vibration durability
- Resists electromagnetic interference
- Voltage signal read by the ECM, so a malfunction can trigger error codes
- Adjustable sensor with bolt mounting
