[QUOTE="Kevin Palmer, post: 790317, member: 54263"] From the FAQ's Diagnostic Trouble Code (DTC) Descriptions P1400 - DPF EGR Sensor Circuit Low Voltage Detected Description The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value. Possible Causes DPFEGR circuit short to GND Damaged DPF EGR sensor VREF short to GND Damaged PCM Diagnostic Aides A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, Recently discussed here, [/QUOTE]
