The sensor measures cylinder compression, intake manifold vacuum, back pressure. All these measurements can be made in one hit. These parameters allow detecting airflows from the combustion chamber, as well as determining the working phases of the valve timing. It is also possible to carry out measurements in other engine systems, within the working range of the sensor, such as fuel system, lubrication and cooling systems.

- from the reverse polarity;
- from the ground fault of the sensor signal output;
- from supplying the voltage to the sensor signal output;
- the sensor case is not connected to the negative wire, so if the sensor is screwed into the spark-plug well and the negative power wire is accidentally connected to the positive terminal of the automotive battery, there won’t be a short circuit.
Diagnosing a timing belt system with the help of a PS16 pressure sensor and MT Pro automotive oscilloscope, connecting the sensor to the engine, oscilloscope tuning, waveform recording while idle running, increased load and cranking. I’ll demonstrate all of this on Seat Ibiza.
In-cylinder compression measuring of a petrol Volkswagen Golf 4 2000 1.6 during cranking using the PS16 pressure sensor and Autoscope automotive oscilloscope (39:47).
The sensor case is made of steel, which reliably protects it from possible mechanical damage and external electromagnetic noise. The coating is black zinc. The connecting thread is М14х1.25. If you need to connect the sensor to another threaded connection, use one of the recommended adapters.
The signal cable is connected to the sensor via a three-pin connector with a latch.

The soft microphone cable with a dense shielding braid is used as a signal cable. BNC is used as a sensor-oscilloscope connector. The power cable is insulated in soft silicone. Clips are used for connecting to the automotive battery.
The sensor is compatible with the MT Pro motor tester, but it can also be used with any other oscilloscope and be connected to any analog channels.
The sensor is meant for recording the forms of pressure pulsations in the intake manifold, crankcase ventilation system or engine exhaust system. This allows estimating alignment accuracy of the value train, defining if the clearance between the piston and cylinder wall is excessive, checking cylinder balance as well as detecting misfiring in the cylinder without taking an engine apart.
Applicable when it is impossible to directly install the PS16 pressure sensor in the spark plug hole. The rigid compression tube allows measurements in deep plug wells.
It is used when it is not possible to screw the PS16 pressure sensor directly into the spark plug hole. The flexible extension allows measurements in the ignition plug wells, which are difficult to access because of an intake manifold or other engine parts.
Used to install the PS16 pressure sensor in the spark plug hole with the M12 thread.
The sensor is designed for diagnosing distributor, DIS and COP systems. Two or more ignition coils are diagnosed one by one. The sensor also receives a signal of synchronization from the first cylinder. It’s used for measuring secondary voltage parameters, accessing ignition spark capability and identifying problems related to high-voltage wires, plugs, caps and coils.
Used to install the PS16 pressure sensor in the spark plug hole with the tapered seat. Often found on Mazda, Ford engines.
