What Does P0148 Mean? OBD-II Code Decreased engine performance is defined as a Fuel Delivery Error The engine control module (PCM) uses a Fuel Rail Pressure Sensor to determine the amount of fuel going to the injectors. If the PCM does not see that the commanded pressure is equal to the actual pressure, the PCM will set code P0148. engine code P0148P0148 fixobd P0148dtc P0148obd code P0148obd2 P0148P0148 car codediagnostic code P0148car code P0148check engine code P0148fehlercode P0148P0148 fiatcodigo P0148codigo falla P0148P0148 kody b??dówcodigo de falla P0148 What are the common causes of P0148 ? Fuel Leaks Faulty Fuel Control Actuator Faulty Fuel Pressure Sensor What are the symptoms of P0148 ? A fuel delivery error may lead to reduced engine performance and possibly engine damage, so a code P0148 should be addressed with some degree of urgency (especially if a strong fuel odor accompanies it). Symptoms of a P0148 code may include: Decreased fuel efficiency Diminished engine performance Excessive black smoke from exhaust The strong odor of diesel fuel Other fuel and engine drivability related codes may be stored How do you troubleshoot P0148 ? If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. Oxygen sensors signal the engine management computer the amount of oxygen present in the exhaust, which is used in determining and controlling the fuel ratio.
