2JZ Sensor Guide – What you need to swap a 2JZGTE

While the 2JZGTE is still a production motor and parts are easily attainable from Toyota, the fact remains that most of the 2JZGTE swaps are coming from JDM Engine Importers which means the motors are used. When you factor in how far the motor must travel, how long they are usually stored and the regularity in which Japanese owners must swap in new engines, and chances are sensors will be broken, missing or simply damaged when you receive them. The last thing you want to find before you start your 2JZ swap is that you don’t have the right 2JZ Sensor or you’ve got a broken one.

Purchasing a used motor from a JDM importer can be a difficult task, because there is simply no way to determine the mileage on the motors you will receive. Most JDM importers quote a generic range of 40,000-60,000 miles but in reality there’s no real way to know. Don’t forget to check out our JDM Engine Purchasing Guide for more details on how you can protect yourself and get the best possible motor at the lowest possible price.

Most of the JDM engines are steam cleaned before delivery, so it’s important to go through your motor to check your sensors so that your engine swap goes as smoothly as possible. So without further ado, let’s take a look at our 2JZ Sensor Checklist and get to work!

2JZ Sensor Checklist

Mass Air Flow Meter

Considering the majority of 2JZ engine swaps will be JDM of nature, chances are you will not opt to wire in a Air Mass Flow Meter as it may complicate your engine wiring and swap. If you are swapping in a USDM 2JZGTE, you will need this for your ECU to operate your motor as it depends on both MAF and MAP signals to orchestrate the fuel and spark in your engine. This 2JZ Sensor is an integral part of your USDM 2JZGTE engine swap.

The part number for the 2JZGTE MAF Sensor part number is 22250-46030, Air Mass Meter and is located in your engine bay connected to your intake tract. For details on how to test your MAF Sensor, check out our How-To Test Your 2JZ MAF Meter tutorial.

Camshaft Position Sensor

The Camshaft Position Sensor is a very important part of your 2JZGTE swap and is located on the cylinder head near the idle air controller. This sensor is connected with a 2 prong weatherproof connector and can fail in your engine depending on it’s condition.

As this sensor provides real time data to the ECU/PCM in regards to camshaft positioning, it is vital that this unit is in good working condition for your engine to operate. Make sure to check out our How-To Inspect your 2JZ Camshaft Position Sensor, which shows you the exact procedure on how to locate, test and replace your CPS. The Toyota part number for this unit is 90919-05007, Camshaft Position Sensor.

There are 2 camshaft position sensors on your 2JZGTE, as shown in the diagram below. You can test the camshaft 2JZ Sensor interchangeably if you believe that just one of them have failed.

Idle Air Controller

The Idle Air Controller ( IAC ) is located on your stock intake manifold near your rear camshaft position sensor. This unit has 2 coolant lines running to it as well as a large 5/8th inch vacuum hose. Testing the IAC 2JZ Sensor is easy to do with the use of a digital multimeter.

The IAC enables the ECU/PCM to control the engine idle by allowing unmetered air to enter into the intake tract, the coolant lines help to bring the unit to operating temperatures as well as dampen the noise from the unit.

Take a look at our How-To test your 2JZ Idle Air Controller and don’t forget to also take a look at our 2JZ 240SX wiring How-To for instructions on how to power the Idle Air Controller. The Toyota Part number for this unit is 22270-46060, Idle Control Valve. Another very important sensor in your 2JZ engine swap on our 2JZ Sensor Checklist.

Manifold Absolute Pressure Sensor

The Manifold Absolute Pressure Sensor ( MAP ) is the unit most enthusiasts will be most concerned with, especially if you are swapping in a JDM Aristo engine. Because this is a three pin 2JZ Sensor, you can test it easily.

As the JDM version has a few differences compared to the USDM model, it is quite a bit easier to get started and running as it does not require a Mass Air Flow ( MAF ) Sensor.

The MAP sensor is located on the intake manifold, connected by a 3 prong weatherproof connector and can be tested using our handy How-To writeup. The Toyota part number for this unit is 89421-12111, Pressure Sensor and you can use this part to simply bypass your AFM/MAF if you so desire at the cost of some part throttle efficiency.

Don’t forget our How-To writeup on the Super AFC and how to wire it into your MAP Sensor and tune your 2JZ engine swap. And we also have a How To Test your 2JZ MAP Sensor

Coolant Temperature Sensor

This sensor gives the ECU a real time reading of the coolant temperature, although it is not to be confused with the 2JZ Thermo-Time Switch.

This 2JZ Sensor gives the ECU a guide on when to use the cold afm maps or when to turn on the cooling fans.

This sensor is located in the cylinder head near the front of the engine and is connected by a 2 wire weatherproof connector. Make sure your wiring is correct for this unit to integrate into your existing dash, especially if you are swapping this into a 240SX.

The Toyota part number for this unit is 89422-35010, Water Temperature Sensor, an essential part of our 2JZ Sensor Guide.

Crankshaft Position Sensor :

The crankshaft position sensor is a very commonly broken sensor as the pigtail that leads out of it can often times be broken or smashed.

This unit is mounted behind the front crank pulley, and provides the ECU real time crankshaft position data. Need to test your crankshaft position sensor? When your 2JZ engine swap doesn’t have spark or won’t start check out this 2JZ Sensor first.

This data is collected by way of a reluctor wheel located behind the crank pulley and gives your ECU data that is vital to engine operation as well as adjusting the ignition timing. The Toyota part number for this unit is 90919-05006, Crank Position Sensor

Air Intake Temperature Sensor :

The Air Intake Temperature Sensor or as Toyota likes to call it the Ambient Air Temperature sensor gives your ECU the correct temperature of the incoming air before entering your turbochargers. The ECU needs this data primarily when it decides that the incoming air charge may be too hot and will adjust your fuel and ignition tables accordingly.

This sensor is located in the intake tract and has a Toyota part number of 88625-14110, Ambient Temp Sensor

Oil Pressure Sensor :

This uniquely shaped 1 pin connector is located in the block and is not to be confused with the lower oil sender.

The Toyota part number for this unit is 83530-0E010, Oil Pressure Sender, and is often confused with the Engine Low Oil sensor that is mounted to the upper plenum of the 2JZGTE Oil pan.

Make sure to check out our Engine Low Oil Sensor testing procedure for the 2JZGTE and don’t forget our How To Swap a 2JZ writeup guide either!

Knock Sensor :

There are 2 of these sensors located in your 2JZ and they are located on the side of your shortblock, and connected by a very unique one pin weatherproof connector.

These sensors are essentially microphones for the ECU to determine whether or not preignition (detonation) is occuring in the engine, and whether or not to act accordingly. As you can imagine in a forced induction application such as this, this sensor is vital to your engine’s operation as it directly impacts longevity and durability. The Toyota part number for this is 89615-22030, Knock Sensor and it’s one sensor on this 2JZ Sensor Guide you don’t want to miss.

Throttle Position Sensor :

The Throttle Position Sensor ( TPS ) is often confused with the sub throttle bodies which are also similar in design and function with draft style throttle plates incorporated into the factory throttle body. Make sure you are checking the true Throttle Position Sensor which is located as shown in the diagram above and is connected by a four wire weatherproof connector.

The TPS signal provides vital information to the ECU in relation to the throttle valve position, which in turn dictates how much air will be entering the engine. While many enthusiasts opt for an aftermarket throttle body, for those sticking to the OEM unit will be best served by checking the operating status of the Throttle Position Sensor.

The TPS Toyota Part number is 89452-22080, Throttle Position Sensor and this unit must be programmed or installed correctly before you can swap a new one onto your throttle body. The Toyota Throttle body part number is 22030-46070, Throttle Body.

This sensor as well as the sub throttle body actuators are some of the most commonly broken sensors on a 2JZGTE when receiving it from the engine importer.

Oxygen Sensor :

Rounding out our 2JZ Sensor Checklist is the 02 sensor.

The Oxygen Sensor ( 02 Sensors if you wish to retain a catalytic converter) allow for the ECU to operate in closed loop mode for gas mileage and engine efficiency. There is a main 02 sensor located in your stock 02 housing, which is before your downpipe and the secondary is usually found after your catalytic converter.

As this sensor is vital to your engines operation and gas mileage, we always recommend purchasing a new Denso 02 universal sensor ( 50 dollar part ) vs the Toyota version ( upwards of 180 ) and do the wiring yourself. If you are wiring your 2JZGTE Engine swap anyways, this part is very easy to do.

The Toyota part number for this unit is 89465-19605, Oxygen Sensor, Oxygen Sensor and the downstream part number is 89465-19595, Oxygen Sensor. If you are installing a wideband 2JZ Sensor for your oxygen sensor, you can run this wiring alongside your current O2 sensor harness.
