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” .
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 test Detroit Diesel engine series 60?
Using either DDDL or DDR, activate PWM #2 and PWM #4 duty cycles and monitor the output pressure from the VPOD. Activate the duty cycle to 50%. Pressure should equal 305-315 kPa (42-47 psi @ VPOD). Note: Both activations must have full linkage travel. Repeat step 3 a total of 3 times.
How does the temperature sensor work in an EGR?
The temperature sensor is supplied a 5-volt reference signal from the ECU and returns a voltage signal to the ECU relative to exhaust gas temperatures in the EGR delivery pipe. The sensor return voltage decreases as exhaust gas temperature increases (sensor operating values are 0.10-5.0 V).
What’s the head bolt torque on a Detroit 60?
Head bolt torque and pattern for a Detroit Diesel 60 series 12.7 L pre EGR – Answered by a verified Technician We use cookies to give you the best possible experience on our website.
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.
Are there any problems with Detroit Diesel Series 60 engines?
Changing the SRS (Synchronous Reference Sensor) and TRS (Timing Reference Sensor) could also help with this issue. These two sensors should be replaced at the same time to maintain proper operation. This particular issue affects Series 60 engines built before 2002.
How does the EGR system work on a VGT engine?
This EGR system works with the VGT operation to create the right turbo drive pressures for the right amount of EGR Flow. The 2003-2007 EGR systems on the older engine models do not have a VGT Turbo, so this EGR operation will work the same way but without regulating the turbocharger. 2. DPF System
How does EGR work on a SCR DPF Doc?
This EGR system works with the VGT operation to create the right turbo drive pressures for the right amount of EGR Flow. The 2003-2007 EGR systems on the older engine models do not have a VGT Turbo, so this EGR operation will work the same way but without regulating the turbocharger.
What causes a Detroit Diesel Series 60 to overheat?
This can indicate a coolant leak. If there is such a leak, you might also notice lower coolant levels in your engine, but things otherwise appear normal. This can lead to an overheated engine. Operators often find that they experience issues with their EGR system on their 14L Series 60 in particular.
Are there any problems with the Detroit Series 60?
This issue did not affect all pre-2002 Series 60 engines, but it was a problem that occurred and could cause catastrophic engine failure. As with most engines, it’s a good idea to keep an eye on your cooling system. Overheating is the cause of many major issues with diesel engines, so maintaining this system can help with many preventable issues.
What kind of lubricating oil does a 1998 Detroit Diesel use?
*Whichever comes first. †Drain intervals shown apply to pre-1998 model year engines. 1998 and newer engines may require a modification to these intervals based on used oil analysis. Refer to publication “Lubricating Oil, Fuel, and Filters”, form 7SE270 (9901), available from authorized Detroit Diesel distributors.
