What does the EGR vacuum do?
It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
What causes faulty EGR?
EGR valves can become stuck ‘open’ or ‘closed’ due to a build-up of soot particles, carbon deposits and dirt from fuel. Motorway driving conditions are the most favourable to your EGR valve as longer, faster journeys allow the engine to get hot enough to get rid of carbon deposits.
What is a EGR valve located?
The exhaust gas recirculation valve, also known as the EGR valve, recirculates exhaust gas back into the intake, mainly in order to reduce combustion chamber temperatures and improve emissions. The EGR valve is usually located near or attached to the intake manifold, with a tube running to the exhaust manifold.
When did the Detroit Series 60 engine come out?
The popular Detroit Series 60 engine was introduced in 1987. This in-line, 4-cycle, 6-cylinder diesel engine uses the innovative DDEC electronic fuel control system to provide engine management reports, answering the high demand for a fuel-efficient heavy-duty engine.
How to check Series 60 EGR section 10.4?
If the supply pressure is between 703-1296 kPa (90-120 psi), perform a VPOD Part Number and Supply Voltage Test “10.4.3.4 VPOD Part Number and Supply Voltage Test and Part Number Check” . Verify repairs. Perform the follow steps to verify the VPOD part number and supply voltage.
How to do an EGR test on a Detroit Diesel?
If the PWM voltage measurement is incorrect and the wiring checks were correct, try a test ECU programmed for EGR or contact the Detroit Diesel Customer Support Center at 313-592-5800. Verify repairs. Perform an Active Codes Test “10.4.3.6 Active Codes Test” .
What should I do if my EGR is not working?
If the EGR valve is not functioning correctly, replace the EGR valve. Visually inspect the EGR cooler for restrictions. If the EGR cooler is restricted, replace the EGR cooler. Visually check the delivery pipe for restrictions. Clean the pipe as necessary to remove restrictions. Verify repairs.
