2JZ Non VVT-i Trigger Information

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.  Non-VVTi engine have a 12x tooth.

Cam Sensor

Two Cam Position Sensors are present on the Non VVTi engine, both are Reluctor sensors with a single tooth pickup
The sensors are located on the LHS of the cylinder head near the intake manifold/injectors with G1 located midway along the engine, and G2 located towards the rear.  The G2 sensor is used with Haltech Terminated Harnesses.

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-).

This model requires the Haltech Trigger and Home Grounds to be Enabled






Trigger Configuration - Non VVT (G2 - Rear Cam Sensor)

Notes:
If OEM Wiring is used such as when an adapter harness is installed, then the Ground Reference should be changed to ENABLED for both Trigger and Home.
If the G1 Mid Cam Sensor is used the TDC Offset will need to be increased by 360 to become 365.
