Diagnostic Codes Table    
Description    Conditions which Generate this Code    System Response    
190-8 Engine Speed Sensor abnormal frequency, pulse width, or period     The Electronic Control Module (ECM) detects a loss of signal from the primary speed/timing sensor for two seconds.
The ECM has been powered for at least three seconds.     The code is logged.
If equipped, the warning light will illuminate.
The ECM will use the signal from the secondary speed/timing sensor.
The engine will be derated. The engine will shut down if both of the speed/timing signals are lost.    
261-11 Engine Timing Offset fault     The ECM detects a faulty signal from both speed/timing sensors.
The ECM has been powered for at least three seconds.     The code is logged.
If equipped, the warning light will illuminate.
The ECM will use a default speed/timing.
The engine may run rough.    
342-8 Secondary Engine Speed Sensor abnormal frequency, pulse width, or period     The ECM detects a loss of signal from the secondary speed/timing sensor for two seconds.
The ECM has been powered for at least three seconds.     The code is logged.
If equipped, the warning light will illuminate.
The loss of signal during start-up will prevent the engine from starting.
The ECM will use the signal from the primary speed/timing sensor.
. If both speed/timing signals are lost the engine will shut down.    The engine uses two engine speed/timing sensors. The primary speed/timing sensor is located on the left hand side of the cylinder block close to the flywheel housing. The secondary speed/timing sensor is part of the fuel rail pump. The primary speed/timing sensor that is mounted on the cylinder block generates a signal by detecting the movement of the teeth that are located on the crankshaft timing ring. The crankshaft timing ring is connected to the crankshaft. The signal that is generated by the speed/timing sensor is transmitted to the Electronic Control Module (ECM). The ECM uses the signal from the speed/timing sensor to calculate the position of the crankshaft. The signal is also used to determine the engine speed.The secondary speed/timing sensor is located in the fuel rail pump. The secondary speed/timing sensor generates a signal that is related to the camshaft position. The fuel rail pump is mechanically connected to the camshaft. The secondary speed/timing sensor detects the movement of the teeth on the timing ring in the fuel rail pump. The signal that is generated by the speed/timing sensor is transmitted to the ECM. The ECM calculates the speed and the rotational position of the engine by using the signal. The secondary speed/timing sensor is required for starting purposes.During normal operation, the secondary speed/timing sensor is used to determine the cycle that the engine is on. When the timing has been established, the primary speed/timing sensor is then used to determine the engine speed and the angular position.The loss of signal to the primary sensor and/or the secondary sensor will result in one of the following faults:
A loss of signal from the secondary speed/timing sensor during start-up will prevent the engine from starting.
The engine will continue to run when only one sensor signal is present from either the primary sensor or the secondary sensor.
A loss of signal from the primary speed/timing sensor during operation of the engine will result in engine operation with a derate.
A loss of signal from the primary sensor and the secondary sensor during operation of the engine will cause fuel injection to be terminated and the engine will stop.The primary sensor and the secondary sensor are interchangeable components. This will allow testing to determine if a speed/timing sensor is faulty.

Turn the keyswitch to the OFF position.
Inspect the connectors for the speed/timing sensors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires in the suspect sensor connector and the sensor connections at the ECM.
Check that the ground connection on the ECM and the negative terminal on the battery are correctly installed.
Check the ground connection on the ECM for abrasions and pinch points.
Check the screws for the ECM connector for the correct torque of 5 N m (44 lb in).
Check the harness for abrasion and pinch points from the suspect se
