If fault code s 146/0 is still active, contact the Detroit Diesel Customer Support Center at 31.Erase fault code memory and verify repairs. Look for heavy soot deposits on the valves.Look for open valves (damaged or stuck).Check for damage to the reed valves as follows:.If fault code s 146/0 is still active, go to step 6.Check the viscous fan for proper operation.Check the radiator hoses for collapsing.Check the fan shroud for proper position.Check fan belt condition for possible slippage.Check airflow through the CAC and radiator.

Refer to the appropriate OEM Vehicle service manual as required.
Check the following vehicle components for proper function. If coolant usage is normal, go to step 5. Clean and replace parts as indicated by inspection. Refer to appendix "7.2.2 Service Information Letters" If coolant usage indicates a leak, perform an EGR Cooler Inspection. If fault code s 146/0 is still active, go to step 4. If resistance is less than 3 Ω, check all contacts and connections. If resistance is greater than 3 Ω, repair open circuit in wire between pin 22 of the 55-pin connector and pin 3 of sensor connector. Measure the resistance between pin 22 of the 55-pin connector and pin 3 of the EGR temperature sensor connector. If fault code s 146/0 is still active, go to step 3. If fault code s 146/0 is no longer active, erase fault code memory and verify repairs. If fault code s 146/0 is active, repair open circuit in wire between pin 28 of the 55-pin connector and pin 1 of sensor connector. "EGR Temperature Sensor Pins and 55-Pin Connector Wires" Bridge pin 1 of the EGR temperature sensor connector to ground and check for active fault codes. If fault code s 146/0 is still active code, go to step 2. Erase the fault code memory and verify repairs. If fault code s 146/1 is active code, replace the EGR temperature sensor. If fault code s 146/0 is the only active code, repair the short between wires for pins 28 to 1 and pins 22 to 3. EGR Temperature Sensor Pins and 55-Pin Connector Wires Control of the EGR valve is routed through pins 11, 42, and 50 of the 55-pin connector. Bad Component (146/12), refer to "4.3.2.5 146/12 - Bad Component"ĭata for the EGR temperature sensor is routed through pins 28 and 22 of the 55-pin connector. 
EGR Valve not Responding (146/7), refer to "4.3.2.4 146/7 - EGR Valve not Responding".EGR Temperature below Normal (146/1), refer to "4.3.2.2 146/1 - EGR Temperature below Normal".EGR Temperature above Normal (146/0), refer to "4.3.2.1 146/0 - EGR Temperature above Normal".SID 146 indicates that during engine operation, the DDEC-ECU received EGR system parameters outside their normal range resulting in one or more of the following fault codes: The Detroit Diesel Diagnostic Link (DDDL) snapshots are not as dynamic on the MBE engines and are usually just used to supplement the DTCs when troubleshooting. Means of solving troubleshooting problems. Therefore, using the DTCs should be the primary

Note: The EGR systems in the MBE 4000 and MBE 900 engines contain fewer components and use simpler control logic than the other series of Detroit Diesel engines.
Do not modify or tamper with the exhaust system or emission control system. If operating an engine in an enclosed area, vent the exhaust to the outside. Always start and operate an engine in a well ventilated area. To avoid injury, use care when working around moving belts and rotating parts on the engine.ĭiesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The response would be to troubleshoot a PID or SID as follows. Performance codes indicate the detection of mechanical failures by the DDEC system.
