Question2005 dodge ram 1500 4x4 5.7 engine Could you tell me what codes P0405 and P0585 mean and what to repair? Thank you
AnswerP0405-EGR POSITION SENSOR CIRCUIT LOW
When Monitored:
With the ignition on. Battery voltage above 10.0 volts.
Set Condition:
EGR Position Sensor Signal is less than the minimum acceptable voltage. One trip Fault.
Possible Causes
(F856) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
(F856) 5-VOLT SUPPLY CIRCUIT OPEN
(K34) EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
(K34) EGR POSITION SENSOR SIGNAL CIRCUIT SHORTED TO THE (K900) SENSOR GROUND CIRCUIT
EXCESSIVE RESISTANCE IN THE (K34) EGR SIGNAL CIRCUIT
EGR SOLENOID ASSEMBLY
POWERTRAIN CONTROL MODULE (PCM
P0585-SPEED CONTROL SWITCH 1/2 CORRELATION (5.7L)
When Monitored:
Ignition on.
Set Condition:
Cruise Switch inputs are not coherent with each other. Example: PCM is reading Switch No.1 as Accel and Switch No.2 as Coast at the same time. One trip fault.
Possible Causes
S/C SWITCH SIGNAL CIRCUITS SHORTED TO BATTERY VOLTAGE
RESISTANCE IN THE S/C SWITCH SIGNAL CIRCUITS
RESISTANCE IN THE (V937) SWITCH RETURN CIRCUIT
S/C SWITCH SIGNAL CIRCUITS SHORTED TO THE (V937) SWITCH RETURN CIRCUIT
(V37) S/C SWITCH NO.1 SIGNAL CIRCUIT SHORTED TO THE (V38) S/C SWITCH NO.2 SIGNAL CIRCUIT
S/C SWITCH SIGNAL CIRCUITS SHORTED TO GROUND
