What is trouble code P0093?
Diagnostic Trouble Code (DTC) P0093 stands for “Fuel System Large Leak Detected.” This code is triggered once the vehicle’s powertrain control module (PCM) detects the possibility of a large fuel leak. On vehicles with diesel engines, the leak is often detected on the high-pressure side of the engine.
What is code P0087?
When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification. Symptoms of a P0087 diagnostic trouble code may include a misfire because of a lean fuel condition, and the vehicle might run rough or lack power on acceleration.
Is there a p0093 code for Isuzu NPR 5.2L?
I pulled an oil sample and had it tested for fuel dilution (because of the P0093 code) came back with a clean bill of health. I should also mention that i inspected ALL the fuel components for possible external leaks and everything is dry as a bone.
How does a fuel system code p0093 work?
When the computer sets this code it senses a large fuel leak in the high pressure section of the engine. The ECM in a diesel always monitors and controls the fuel pressure from the fuel injector pump to the injectors as long as the engine is running. To set a code P0093 the ECM must sense a sudden large drop in fuel pressure within the system.
How is fuel pressure regulated on an Isuzu?
Fuel is drawn from the fuel tank via a feed pump and then pumped into the fuel rail by two plungers, all of which are internal to the fuel supply pump. This high pressure is regulated by the engine control module (ECM) using the fuel rail pressure (FRP) regulator dependant upon values from the FRP sensor attached to the fuel rail.
