Crankshaft and camshaft sensors

Tips for connecting hall sensors

The hall sensor allows the use of unshielded wire. There are sensors that need 5v power instead of 12v.

Tips for connecting inductive sensors

The wire of an inductive sensor should be shielded along its entire length. The wire should be routed as far away as possible from coils, high voltage wires, starter, alternator, fan, and other powerful devices. If the sensor is 3-wire, the third pin is the shield. It should be connected to the shield of the wire. The shield should be connected to ground on one side only - near the ECU.

Determine which of the contacts to connect to the screen, you can use a tester. Find a pair of contacts between which the resistance is from 200 Ohm to 5 kOhm - these are contacts 1 and 2. Therefore, the third contact that is not probed is the screen.

You can use the circuit below to determine polarity. If the polarity is correct - the LED will light up when a metal object is rapidly approaching the sensor. If the polarity is incorrect, the LED will light up when the object moves away from the sensor.

Crankshaft position sensor

Hall

Connect the sensor to the DH5 input and check the "DPKV on DH5" box

Inductive

Camshaft position sensor

Hall

The sensor that is used for synchronization can only be connected to the DH1 input The other sensors can be connected to other available inputs (DH2, DH5)

If there are not enough inputs, you can connect the hall sensors to the inductive inputs VR3,VR4 (DH3,DH4)

Inductive

The sensor used for synchronization is connected only to the VR2(DNO) input according to this diagram

The remaining sensors may be connected to other free inputs (DH3, DH4)

Caution

Improper connection polarity will cause synchronization failure at certain RPMs.

TDC sensor

Used on Audi 5-cylinder engines.

Caution

If the polarity of the connection is incorrect, synchronization failure will occur at certain RPMs.
