New and updated Guided tests in PicoScope Automotive

New FirstLook™ Automotive Engine Diagnostics Sensor tests

We believe in fast and efficient non-invasive diagnostic testing. As such, we are releasing 3 additional FirstLook™ Automotive Engine Diagnostics Sensor guided tests.

The expanded set of tests help you capture exhaust, inlet, (gasoline multi-point injection) fuel rail and crankcase pressure pulsation waveforms, which are especially useful for the rapid diagnosis of misfires, compression losses due to piston blow-by, blocked injectors, or exhaust and inlet and valve issues. By also capturing an ignition reference source, the tests allow you to pinpoint the problematic cylinder.

Intake manifold pressure pulsations during running: the purpose of this test is to assess the engine condition by using the FirstLook™ sensor to observe intake manifold pressure pulsations during running.

Crankcase pressure pulsations during cranking: the purpose of this test is to assess the engine condition by using the FirstLook™ sensor to observe crankcase pressure pulsations during cranking.

 

Crankcase pressure pulsations during running: The purpose of this test is to assess the engine condition by using the FirstLook™ sensor to observe crankcase pressure pulsations during running.

These new tests add to and complement the existing, recently updated and released, tests:

-  Exhaust pulsation during cranking.
- Exhaust pulsation during idle.
- Intake manifold pulsation during cranking.
- Fuel pressure regulator vacuum pulsation during idle.

Updated WPS500X pressure sensor tests

As part of our ongoing refurbishment of all our guided tests, we are releasing 2 x updated WPS500X pressure sensor guided tests:

The two updated tests help you to diagnose low pressure, vacuum-type, fuel supply faults and back-leakage issues with common rail diesel solenoid injectors:    

Common rail diesel solenoid injector back-leakage: the purpose of this test is to use the WPS500X pressure transducer to measure and compare Common Rail Diesel (CRD) solenoid injector back-leakage pressure pulsations within a low-pressure fuel return system.

Fuel pressure - negative priming (diesel): the purpose of this test is to verify the integrity of a fuel supply system (vacuum type) by checking its ability to create and maintain negative pressure (i.e. a pressure below atmospheric pressure).

 

Please note: These Guided tests are being rolled out in PicoScope Automotive and will be available in the upcoming release of PicoScope 7 Automotive beta.
