NOTE
0190-08 Engine Speed
Sensor Abnormal
Always inspect harness connectors that are involved in the circuit. Poor
connections can often be the cause of a problem in an electrical circuit.
Period
Verify that all connections in the circuit are clean and secure and that all
connections are in good condition. If a problem with the connection is
found, correct the problem and verify that this malfunction or diagnostic
code is active before performing this procedure.
Perform open or short-circuit test at each harness connection to identify
the correct harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
DIAGNOSTIC CODE SET CONDITION
Transmission/Chassis ECM Detects Abnormal Pulse Width or Frequency From
Transmission EOS (Engine Output Speed Sensor).
POSSIBLE CAUSE
Main Cab Wring Harness High Resistance, Open, or Shorted.
Engine Interface Wring Harness High Resistance, Open, or Shorted.
Transmission EOS.
Transmission/Chassis ECM.
Test Step 1. Inspect Transmission
EOS for Damage.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-296-10).
2. Disconnect connector CL-C12
