P140A
P140A-00 Exhaust gas recirculation sensor C – circuit low
Exhaust gas recirculation (EGR) valve circuit (left-hand bank) high resistance
Exhaust gas recirculation (EGR) valve circuit short circuit to ground
Exhaust gas recirculation (EGR) valve fault
Exhaust gas recirculation (EGR) valve potentiometer signal less than minimum (sensor B)
NOTE: Using a diagnostic system perform the Turbo, EGR and air path dynamic test routine
Check the exhaust gas recirculation valve and circuits. If the DTC is present on its own then check the turbo, if it’s a common fault, then the fault is an EGR wiring fault, as wiring is common. Refer to the electrical circuit diagrams and check – EGR Valve Position Sensor Bank B – Signal – circuit for short circuit to ground, high resistance
P140A-21 Exhaust Gas Recirculation Sensor C Circuit Low – signal amplitude < minimum Signal amplitude less than minimum Exhaust gas recirculation valve Potentiometer signal less than minimum (sensor B) Refer to the electrical circuit diagrams and check - EGR Valve Position Sensor Bank B - Signal - circuit for short circuit to ground
