2013年8月13日 · The EGR differential pressure sensor, and the EGR mixing tube are going to get just as dirty, so start there. Replace the EGR differential pressure sensor and clean the EGR mixing pipe, and the EGR temperature sensor before even considering replacing the EGR valve. The next step is to clean the EGR valve to see if the problem changes or goes away.

2021年3月5日 · 07 international 9400i with 06 Cummins ISX cm870. Had tune-up (over head) done at cummins shop threw a 2359 code while there. They tested the turbo actuator and it was fine, they then put shop air to the air control valve and it was bad. We bought a …

2012年3月20日 · 2372 Fuel Filter Differential Pressure - Data Valid but Above Normal Operational Range - Moderately Severe Level 2373 Exhaust Gas Pressure Sensor Circuit - Voltage Above Normal, or Shorted to High Source 2374 Exhaust Gas Pressure Sensor Circuit - Voltage Below Normal, or Shorted to Low Source

2020年4月19日 · File: 454-t06-33832 Leaking EGR differential pressure sensor mounting surface Page 3 of 8 Solution: S00001114 Verification Conditions • Turn keyswitch OFF. Action • Remove the EGR differential pressure sensor. Refer to Procedure 019-370 • Inspect the o-rings between the EGR differential pressure sensor and the mounting surface. Refer to ...

2013年4月7日 · EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed. Exhaust gas pressure - 120-150" Hg - Low could indicate a failing turbo. Intake manifold pressure - 10-14" Hg - Low could indicate boost or air to air leaks.

2014年10月22日 · Now, about two month later, getting the codes again. Temp, water pressure, oil all normal. Any ideas? The codes come in pairs. This time around I was going to put in a EGR diff pressure sensor again and maybe a Exhaust Gas Pressure Sensor, but just put them in myself and save labor cost. Engine Exhaust Gas Recirculation Differential Pressure ...

2023年2月2日 · Codes 2961 egr temp data valid but above normal, 3342 egr cooler efficiency data valid but above normal are inactive. Customer replaced dpf, scr, doc, dpf differential pressure sensor and tubes, egr differential pressure sensor. Truck was still derating. I reset life on emissions filters and ran a regen, it passed the regen and temps looked good.

2013年4月7日 · DPF DIFFERENTIAL PRESSURE: 0.1hg AFTERTREATMENT FUEL PRESSURE: 14.4psi CRANKCASE PRESSURE: 0.1 inh20 EXHAUST GAS TEMPERATURE: 390-520F (fluctuating.. keeps jumping up and down might be a possible cause? I also saw it jump to 1000F and back down to 300-500F) EGR DIFFERENTIAL PRESSURE: 0.2 inhg EGR …

2009年2月4日 · Is it actually erratic exhaust pressure? Next step would be a voltmeter teed into the supply and ground to see if a signal is dropping off / wandering. It looks like it has a common power with 2 other sensors so it could be an issue on another sensor but only affecting this one like the dpf differential sensor killing the tps on the isx.

2018年11月25日 · Common causes for this code are: 1) DPF differential pressure sensor failure 2) Fuel rail pressure relief valve failure 3) Loose injector high-pressure connector 4) After-treatment DPF failure 5) ECM calibration. I hope this helps.
