Example uses for the WPS500X Pressure Transducer

Case studies

Guest case study: Using dual in-cylinder pressure transducers
The team at Autonerdz use a Pico Pressure Sensor Kit to diagnose and fix a 2011 Jeep Cherokee.

Triumph investigation
We were recently asked to assist with the development, set-up and ultimately the tuning of a rather unique motorcycle. The request turned out to be a fascinating adventure into Motorbikes!

Brake Booster Failure
When applying the foot-brake, the brake pedal appears hard to press intermittently whereby the customer has to apply more effort in order to bring the vehicle to rest. Upon the next brake pedal use the feel of the brake pedal and the effort required to stop the vehicle returns to normal! The symptom had been very intermittent regardless of temperature/road condition and been evident for over two weeks.

Engine non-start
The engine is a non-start after a major engine overhaul. Compressions and valve timing have been checked and are correct.

Misfire
The topic of this case study is not so much "How we managed to diagnose the fault in question" but more about the multiple options at our disposal when it comes to diagnosing component failure.

Sudden power loss
I admit that the fix is probably quite obvious using the parts darts technique or best guess scenario, but I thought this particular job demonstrated the use of the WPS500 as an everyday aid to speed up the diagnostic process.

Misfire
This story concerns an employee of Pico Technology and their journey to the office. About one mile from work the owner of this 54,000 mile Smart Fortwo started to experience a very noticeable misfire.

Variable nozzle turbine pressure control
I was fortunate enough recently to get hold of a WPS500X Pressure Transducer and looked forward to using it right away. It didn’t take long before I found a perfect excuse to switch it on: the Variable Nozzle Turbine (VNT) boost control.
