Sensor Information

Crank/Cam Sensor

The turbo models of this engine all use a Crank Position Sensor and a Cam Position Sensor.   Some aspirated models use a Distributor instead of a crank and cam sensor.


Crank Sensor

Crank sensor models of the 2JZ and 1JZ use a crank trigger located as part of the timing belt drive gear on the crank with the sensor near the alternator. VVTi models have a 36-2 (36 teeth with 2 missing teeth.

Distributor

A 3x Reluctor trigger system is used on the 2JZ-GE engine.  This has a 24x tooth pickup with a single Reluctor pickup (NE), and has a second 1-tooth pickup that has 2x separate sensors (G1 and G2) with only one of the pickups required for Haltech use.  All sensors use a common shared wire back to the ECU (G-).
