SUBJECT: Throttle Position Sensor (TPS)
Voltage Too High



If an Evinrude E-TEC outboard will not accelerate above idle speed and no other faults or issues are found, the Throttle Position Sensor (TPS) voltage may be set too high (exceeding approximately 0.85 V).


IMPORTANT: First, make sure the throttle is fully
closed when starting the engine. A partially open
throttle may cause the TPS voltage to be too high.

When rigging an Evinrude E-TEC outboard, make sure the throttle cable is adjusted so the throttle lever is against the idle stop when the outboard is at IDLE and also returns to the idle stop when moved. Then use one of the Evinrude E-TEC Diagnostic Software programs to verify that the TPS voltage is approximately 0.5 V.
For the correct test procedure, refer to "Sensor Resistance Tests" in the ELECTRICAL AND IGNITION section of the Evinrude E-TEC Service Manual. Also refer to the User's Guide for the diagnostic software.
