Characteristic of Camshaft Position Sensor for Perodua Alza 2010 and how to test its genuine original feature

As described by DENSO the manufacturer of OEM parts for Toyota and Daihatsu - the camshaft position sensor is part of the engine's timing component that work along the crankshaft position sensor to detect the best timing and deliver the data to the ECU to command spark plugs firing and fuel injections as well as intake valve and exhaust valve open / close operations. It is made with delicate components consist of magnetic elements. 

Here we are not going to go through the detail but simple general real life maintenance to keep it working at the most optimum level. 

Note that since the camshaft position sensor consist of magnetic element it will contracted some tiny debris of engines' wears over time and obstruct its effectiveness to deliver data to the ECU. Therefore periodical maintenance should be perform to clean the sensors. 

• If you are cleaning it using throttle body carb cleaner make sure it is dry before installing back to the car.
• Do not use cloths or any materials that generate electrostatic charges when rubbing it onto the surface of the camshaft position sensor to avoid damaging the magnetic element inside it.

Optimum performance of camshaft position sensor is equally important as the crankshaft position sensor as they work hand in hand to keep the best timing for combustions (spark plugs, fuel injectors, oil control valve solenoid).

Where is the camshaft position sensor location on Perodua Alza car?

It's located on the right hand side of the engine (from front view) below the MAP sensor. Sometimes it is hidden by the engines wiring harness intersections. The bolt spanner size is 10mm. 

How to determine the originality of camshaft sensor whether it is genuine or fake (replica, imitation, knock off)

1. Perodua Alza 2010 uses camshaft position sensor with product code 90919-05024 made by DENSO
2. The camshaft position sensor only has two wires
3. On the connector has written word "JAPAN" (protruding) and "ND" (engraved) then DENSO (protruding) see picture below.
4. On the tip surface has a ring round shallow indent - this where metal debris usually stick when it's get dirty. - See picture below
5. Has engraved TOYOTA word and part numbers on the camshaft position sensor
6. Resistance = 2100 Ohms 2.1 kOhms
7. Sensor Type = Inductive Sensor
8. Voltage = 12V
9. Fitting Depth = 30mm or 3cm
10. Number of pins = 2

Other OEM camshaft position sensors manufacturer have resistance between 2.1 kOhm ~ 2.2 kOhms
