Common Failure Symptoms No start Rough idle Loss of power Hesitant acceleration Intermittent engine performance Common Causes of Failure Due to its position underneath the vehicle, the driver module is sensitive to road debris and other contaminants causing the exterior shell to corrode, opening the wa...
Safety considerations: Sudden power failure while driving due to fuel pump failure can be dangerous, especially in certain situations like entering a highway or driving in heavy traffic. This can affect the ability to control the vehicle and respond effectively to road conditions. Risk ...
Most vehicles with fuel injection utilize an electric fuel pump located in the fuel tank to supply sufficient volume and pressure to the injectors. Fuel is under pressure as it enters the fuel injector. The injector is a solenoid activated by the powertrain control module (PCM). The amount of...
Bad fuel pump Engine vacuum leak (including EGR valve failure) Faulty oxygen sensor Mass air flow (MAF) or Manifold Air Pressure (MAP) sensor failure What are some P02A6 troubleshooting steps? If there are MAF or MAP related codes present, diagnose and repair those before attempting to diagnos...
The control module writes the operating conditions to the Freeze Frame and updates the Failure Records. The control module illuminates the malfunction indicator lamp (MIL) when one of the following occur: • The control module detects the same fuel trim failure during 2 consecutive trips. • ...
The fuel line feeds the fuel to an inlet of the transfer pump or fuel pump, which operates to pressurize the fuel for delivery to a fuel injector. Various mechanical and electromechanical linkages exist for fuel delivery, such as distributor-type pumps or electronic control module (ECM) systems...
When I come across a stored code P0094, it generally means that the powertrain control module (PCM) has detected a substantial decrease in fuel pressure. Fuel pressure specifications vary from one manufacturer to another and the PCM is programmed to monitor fuel pressure according to these specifi...
I also have 08 Burb, but have different symptoms (high oil consumption, blue exhaust smoke at start, and now a really rough start after sitting overnight). How do you know if the lifter has failed? I have no other engine problems and I’d like to fix the issue. Do you thi...
