Diagnostic Trouble Codes
CDL Code and Description Conditions that Generate the Code System Response
190-8 Engine Speed : Abnormal Frequency, Pulse Width, or Period The signal from the primary engine speed/timing sensor is intermittent or the signal has been lost. The engine will use the signal from the secondary engine speed/timing sensor for engine speed/timing.
The code is logged.
342-8 Secondary Engine Speed Sensor : Abnormal Frequency, Pulse Width, or Period The Electronic Control Module (ECM) detects an abnormal signal frequency. The code is latched in the active state until the power to the ECM is cycled.
The offset for the timing calibration is set to zero while the diagnostic code is active.
The sensor is ignored. The engine speed is calculated by using only the signal from the primary speed/timing sensor.
The code is logged. The ECM provides the engine speed/timing sensors with a regulated voltage of 8.0 0.5 VDC. The engine speed/timing sensors provide a pulse signal to the ECM. The signal is created as the timing reference gear rotates past the pickup of the engine speed/timing sensors. The timing reference gear is mounted on the rear of the left camshaft.
