Abstract: A dual path exhaust gas recirculation (EGR) system for an engine includes a common EGR intake path and first and second low pressure EGR paths including respective first and second EGR valves. 0405 - EGR Control Circuit Sensor A Circuit Low 2285 - Injector Control Pressure Sensor Circuit Low I just replaced the EBP and ICP sensor and cleared codes and drove it down the road and they came up again. The configuration of an EGR system depends on the required EGR rate and other demands of the particular application. The fault code re-appears immediately I have cleared it. So, when I went in to get my oil changed I asked if they could run a diagnostics for me. An extensive range of operating modes was considered at different engine part-load conditions, starting from the reference one without EGR, then considering the simple activation of the HP or LP EGR circuit, followed by the simultaneous application of high and low pressure recirculation and the addition of variable geometry turbine (VGT) control.

They can become problematic after buildup of carbon on the valve or failure of its internal control system that operates the valve. When the EGR solenoid is activated, or turned ON by this process, it closes the vacuum passage to the EGR valve, thus making it inoperative, supplying no EGR to the engine. The 7760 in the USA market have emissions controls such as DPF and EGR. Using high sulfur fuel (greater than 500 PPM sulfur) can cause corrosive damage to the EGR valve and DPF. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value. It is heats up quickly, then the EGR is open at idle, and it should not be. 0405 - EGR Control Circuit Sensor A Circuit Low 2285 - Injector Control Pressure Sensor Circuit Low I just replaced the EBP and ICP sensor and cleared codes and drove it down the road and they came up again.
