Restriction or leak detected in the intake plumbing between the air filter and the mass-air-flow sensor on ban…
The ECU detects an excessive intake restriction. Either the air filter is heavily clogged or an obstruction in…
The ECU detects unmetered air entering between the mass airflow sensor and the throttle body. The actual airfl…
The ECU detects unmetered air entering downstream of the throttle body. Typical sources are leaking intake-man…
A general electrical fault on the injector control pressure (ICP) sensor — used on HEUI (Hydraulically actuate…
The injector control pressure (ICP) sensor on HEUI diesel systems reports a value that does not match expected…
The voltage of the injector control pressure sensor is below the calibrated minimum. The signal indicates eith…
The voltage of the injector control pressure sensor is above the calibrated maximum. Likely a short to supply …
The injector control pressure sensor signal is intermittently lost or out of range. Often caused by intermitte…
ICP is above the upper threshold during operation. Typically the injection pressure regulator (IPR) is stuck c…
ICP remains above threshold after engine shutdown — pressure does not bleed off as expected, indicating a stuc…
Fuel pressure regulator A has been detected in a state that the PCM considers unsafe and the engine has been s…
Fuel pressure regulator A cannot maintain target pressure — measured pressure stays below the lower control li…
Fuel pressure regulator A cannot reduce pressure below the upper control limit — typically a stuck-closed retu…
The adaptive learning offset for fuel pressure regulator A has reached the lower limit. Long-term drift indica…
ICP is below the lower threshold — typically IPR stuck open, leaking high-pressure oil rail, or weak HP oil pu…
During cranking, ICP does not build up enough to fire injectors. Typical no-start condition on HEUI engines fr…
ICP signal is unstable or jumps — connector or sensor issue, or air in the high-pressure oil rail. A flow-devi…
The high-pressure fuel pressure regulator (volume control or pressure control valve on a direct-injection rail…
Electrical fault on the control line to the high-pressure fuel pressure regulator solenoid. Without a working …
Drive voltage to the second fuel pressure regulator solenoid is below the lower limit. On common-rail diesels …
Drive voltage to the second fuel pressure regulator solenoid is above the upper limit — short to supply or ope…
