How does the camshaft and crankshaft correlation code work?
This will confirm if the camshaft and crankshaft correlation codes are real or if there is an issue with the sensor. With some crank position sensors on the front of the engine, the bracket that holds the sensor can be bent and change the air gap between the sensor and ring.
How to compare camshaft and crankshaft sensor waveforms?
The purpose of this test is to directly compare the relative positions of the Crankshaft position (CKP) and Camshaft position (CMP) sensor waveforms and features. View connection guidance notes. Use manufacturer’s data to identify the crankshaft and camshaft sensor signal circuits. Connect PicoScope Channel A to the crankshaft circuit.
What should the voltage be on the camshaft sensor?
Stable voltage levels, whether around 0 V or around 5 V, on both channels. Clean transitions between the digital signal voltage levels, on both channels. No excessive hash or intermittent signal drop outs, on either channel. Overall switching frequencies that increase with increasing engine speed, on both channels.
How many turns does a crankshaft sensor capture?
Adjust your time scale to capture at least three turns of the crankshaft on a screen. Like wheel speed sensors, engine position sensors can be passive (floating) or active. In the case of engine position sensors, inductive (floating) or hall effect. Inductive sensor setups typically have two signals.
How to check the camshaft and crankshaft correlation?
Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they’re not loose or damaged or that they haven’t sheared the key that aligns them. If they are properly installed, replace the sensor. If the signal appears normal, then check the timing chain/belt for proper alignment.
How to check Mazda p0016 crankshaft and camshaft correlation?
If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 Mazda code will set. First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns.

Where are the crankshaft and camshaft sensors located?
Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select Crankshaft sensor (Hall effect) or Camshaft sensor (Hall effect). An engine’s CKP and CMP sensors provide the Engine Control Module (ECM) with critical engine speed, position, and timing reference data.
