NEW DPF AND TURBO BOOST TEST KIT
From Diesel Help Australia
As well as diesel diagnostics training, Diesel Help Australia provides diesel diagnostic support to more than 200 trade members in Australia and NZ.
Clinton Brett, the Founder and Trainer of Diesel Help Australia, and his team witness a high level of diagnostics involving DPF and turbo faults.
Without the correct guidance and test equipment, popular fault codes relating to EGR, turbos and DPFs can be easily misdiagnosed.
To assist with reducing wasted hours diagnosing and the unnecessary replacements of components, Clinton says he has developed easy to adapt diagnostic equipment, the DPF and Turbo Boost test kit.
“Due to the pandemic, face to face training reduced dramatically yet resulted in a sharp increase in our membership over the past two years,” Clinton said.
“We’ve experienced several cases where the DPF differential pressure sensor was reading incorrectly.
“A difference in pressure of up to 70 kPa from what has been seen on the scan tool has been found in some instances.”
One of these cases is included in a Diesel
Help Australia recorded webinar which was delivered live at the 2021 USA Vision Hitech Virtual Training Expo and is available to view at
The kit includes two liquid filled analogue gauges with a range of 0 to 60 kPa (0 to 8.7psi) which is capable of reading low pressures at idle in a good DPF and a Turbo boost gauge 0 to 400kPa (0 to 58psi) to read the highest intake pressures for diesels.
The DPF gauge connects via a barbed T on the pressure side of the DPF differential sensor and the turbo test gauge is connected via a hose to an engine mounted adaptor which was designed, engineered, and made in Australia.
The testers can be used to confirm the Manifold Absolute Pressure (MAP) sensor and DPF differential pressure sensor data on the scan tool is correct.
“They do fail! Our technical bulletin library includes faults found with Isuzu Dmax, Mitsubishi and soon to be released, the 2020 Hilux,” Clinton said.
“Failures can be caused by DPF, and MAP sensors exposed to extreme conditions including high temperatures, condensation, oil, carbon, dust, and vibration.
“Conditions like this damage vital sensors resulting with incorrect information sent to the ECU. As a result of this inconsistent data, symptoms may occur including poor performance or fault codes forcing the engine to derate and illuminate the engine light.”
The Turbo Boost tester is suitable for applications fitted with a Boost/MAP sensor and the DPF tester is suitable for DPF fitted diesel engine.
