Description
Denso crankshaft position sensor for Nissan 350Z HR and 370Z models. It monitors crankshaft position and engine speed, supplying the ECU with the signal required to coordinate ignition and fuel-injection timing.
This is the lower-mounted crankshaft sensor and is not one of the engine’s camshaft position sensors. One sensor is required per vehicle.

Nissan 350Z HR · 2007–2008 · VQ35HR

Why Choose Denso?
- Denso is a major original-equipment manufacturer of engine-management sensors.
- Application-specific sensor body, mounting point and three-pin connection for the listed HR and VHR engines.
- Clearly documented Denso and Nissan reference numbers make identification easier before ordering.
A crankshaft-sensor fault code, stalling or a no-start condition does not confirm sensor failure by itself, as wiring, connector, power-supply or signal-wheel faults can produce similar symptoms.
Camshaft Sensor Required Instead?
This listing is for the crankshaft position sensor. For an applicable 370Z camshaft position sensor, see the Denso CAS2044 camshaft position sensor.
Please Check Before Ordering
This sensor suits the 350Z HR and 370Z applications listed above. It is not the correct crankshaft sensor for 350Z DE or RevUp engines.
Confirm whether the required component is the crankshaft or camshaft position sensor, then compare the connector, mounting point and original part number.
