One of the most frequent questions we are asked here at Pro Street is “where is my camshaft position sensor located?” or “How can I test my camshaft position sensor?”. It’s a fair question considering the number of 2JZGTE engine swaps there are out there, after all it’s still a production engine. Today well be looking at how to test your 2JZ Camshaft Position Sensor.
We’ve decided to take some time to take a look into this process on our own Project SC, in which we are removing the 2JZGE and swapping in a 2JZGTE from a 1997 Toyota Aristo. So let’s take a look at How To Test Your 2JZ Camshaft Position Sensor.
The camshaft position sensor is a 2 pin unit that is connected using a Delrin type weather proof connector, this sensor is located in your cylinder head.
The 2JZ is a tremendously stout engine with a legion of fans and followers most popularized here in the US by the Toyota Supra, one of the true Japanese Supercars. The 2JZGTE camshaft position sensor is a hall effect type sensor, and is located near the rear of your cylinder head.
When testing your camshaft position sensor, most people are looking for the reason as to why their car is not starting or has intermittent ignition problems. As the camshaft position sensor provides a real time positioning of the engine to the PCM, this is a very important reading for your vehicle.
This how to assumes you have good mechanical skill and are comfortable using a voltmeter, if you are unfamiliar with a voltmeter please ask someone to give you a hand.
First unplug your crank position sensor, for another look at where this sensor is located on your 2JZ, take a look at this picture
There are 2 operating temps that Toyota outlines when you are testing this unit, cold and hot operating ranges that will return a different value depending on the temp of the sensor at hand.
Cold Operating Temperature : from -10 degrees C to 50 degrees C ( 14 degree F to 122 degree F )
Hot Operating Temperature : from 50 degrees C to 100 degrees C ( 122 degree F to 212 degree F )
Disconnect the PCV rubber hose to give yourself some more operating room under the hood, and then disconnect the 2 pin connector that leads to the camshaft position sensor.
Using your ohmmeter, measure the resistance from one pin to the other by placing the red ( positive ) lead to one terminal and the negative ( black ) lead to the other.There are 2 manufacturers that are OES ( Original Equipment Suppliers ) for Toyota in regards to the camshaft position sensor.
One is NipponDenso and the other is Aisan, for more information on OES or OEM suppliers, check out our FAQ sheet on our OEMSPEC program.
Nippon Denso camshaft position sensor COLD – 835-1400Ω
Aisan camshaft position sensor COLD – 985-1600 Ω
Nippon Denso camshaft position sensor HOT – 1060-1645Ω
Aisan camshaft position sensor HOT – 1265-1890 Ω
Toyota specifies this part number as 90919-05007 and we do not recommend aftermarket of offshore versions of this sensor.
If your sensor falls outside of these operating ranges in resistance, then you must replace the camshaft position sensor in question with a new unit. Hopefully this guide has shown you How To Test Your 2JZ Camshaft Position Sensor, but we are always here to help with friendly people.
