CYLINDER GP-COUPLER 1382289 - Caterpillar

Which Generate This Code:This diagnostic code is designed to detect the loss of the 5 Volt supply at the sensor connector.The Electronic Control Module (ECM) detects the following conditions:
The engine speed is more than 1000 rpm.
The intake manifold pressure is within the acceptable range.
No 0262 codes for the 5 Volt supply are active.
Diagnostic code 0168-01 is not active.System Response:If equipped, the warning light will come on. The diagnostic code will be logged.The ECM will flag the intake manifold pressure as being invalid. A default value is used for the intake manifold pressure.Note: Any open circuits or short circuits in the signal wire for the oil pressure may reset this diagnostic.For engines with an electronically controlled wastegate, the current for the wastegate solenoid will be set to a default value while this code is active. This will cause the engine to have poor acceleration but the default setting will prevent any overpressure in the intake manifold which could be caused by an overspeed of the turbocharger.The engine will be derated.This diagnostic code will detect the loss of the 5 Volt supply to the sensor.Test Step 1. Perform the following diagnostic procedure: Engine Pressure Sensor Open or Short Circuit - TestResults:
OK - STOP
