Barometric Pressure Sensor
Circuit - Voltage Below
Normal or Shorted to Low
Source. Low signal voltage
detected at barometric pressure
circuit.
Engine power derate.
190

Engine Crankshaft Speed/
Position - Data Valid but
Above Normal Operational
Range - Most Severe Level.
Engine speed signal indicates
engine speed above engine
protection limit.
Fuel injection disabled until
engine speed falls be- low the
overspeed limit.

Sensor Supply 3 Circuit -
Voltage Below Normal or
Shorted to Low Source. Low
voltage detected on the + 5
volt sensor supply circuit to
the engine speed sensor.
Possible hard starting and
rough running.
3511
{3}
Sensor Supply 3 Circuit -
Voltage Above Normal or
Shorted to High Source. High
voltage detected at sensor
supply number 3 circuit.
Possible hard starting and
rough running.

Wheel-Based Vehicle Speed -
Data Erratic, Intermittent, or
Incorrect. The ECM lost the
vehicle speed signal.
Engine speed limited to
Maximum Engine Speed
without VSS parameter value.
Cruise control, Gear Down
Protection, and Road Speed
Governor will not work.

{10}
Wheel-Based Vehicle Speed
Sensor Circuit, Tampering Has
Been Detected - Abnormal
Rate of Change. Signal
indicates an intermittent
connection or VSS tampering.
Engine speed limited to
Maximum Engine Speed
without VSS parameter value.
Cruise control, Gear- Down
Protection, and Road Speed
Governor will not work.

Fan Control Circuit - Voltage
Below Normal or Shorted to
Low Source. Low signal
voltage detected at the fan
control circuit when
commanded ON.
The fan can possibly stay on
continuously or not run at all.
