How do I fix code P008A RAM?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P008A RAM code
The cost of diagnosing the P008A RAM code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P008A RAM Description
The Powertrain Control Module (PCM) provides the Fuel Rail Pressure Sensor with a 5-Volt supply and sensor ground and receives a signal voltage back from the Fuel Rail Pressure Sensor. This sensor signal voltage changes based on the pressure in the fuel rail. The PCM will light the MIL lamp immediately after the diagnostic runs and fails. During this time the customer may experience the power and/or speed derate. The PCM will turn off the MIL light after the diagnostic runs and passes in four consecutive drive cycles. The Diagnostic Trouble Code (DTC) will set when the Powertrain Control Module (PCM) detects that the Low-Pressure Fuel Delivery pressure is below a calibrated value for a calibrated amount of time.
