Illustration 1 g01045605
Schematic diagram for the inlet manifold temperature sensorThe engine is equipped with a remote control panel that includes a status control module and air/fuel ratio control.
Illustration 2 g01045606
Schematic diagram for the inlet manifold temperature sensorThe engine is configured for Canadian Standards Association (CSA). The engine is equipped with an optional remote control panel with air/fuel ratio control.Test Step 1. Inspect the Electrical Connectors and the Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Thoroughly inspect each of the following connectors:
J1/P1 connectors
Connectors for the inlet manifold temperature sensor

Harness side of the P1 connector (P1-2) +10 VDC (P1-3) Ground for the sensors (P1-27) Signal for the inlet manifold temperature
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the inlet manifold temperature sensor.
Check the harnesses and the wiring for abrasion and for pinch points from the inlet manifold temperature sensor to the ECM.Expected Result:The connectors, pins, and sockets are connected properly. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good condition with proper connections. Proceed to Test Step 2.
Not OK - The components are not in good condition and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary.STOPTest Step 2. Check for an Open Circuit
Disconnect the connectors for the inlet manifold temperature sensor.

Engine speed sensor for the ECM
Disconnect the connectors for the engine speed sensor for the ECM.
Disconnect the J1/P1 connectors.
Measure the resistance between the points that are listed in Table 1. During each measurement, wiggle the wires in the harness in order to check for an intermittent problem. Be sure to wiggle
