Trouble Code: P0116



Engine Coolant Temperature (ECT) Sensor Performance

Possible Causes:



After starting the engine, the ECT sensor temperature should rise steadily, then stabilize after the thermostat opens.
 
Test the ECT sensor at various temperature levels in order to evaluate the possibility of a skewed sensor. A skewed sensor can result in a driveability condition. Refer to Temperature Versus Resistance .
 
Inspect for the correct operation of the engine cooling system and verify the correct coolant level.

Fuel Trim System Lean

Possible Causes:



The system will become lean if a fuel injector is not supplying enough fuel - P0171 or P2187.
 
A lean condition could be present during high fuel demand due to a fuel pump that does not deliver enough fuel, a plugged fuel filter, or a restricted fuel pipe - P0171 or P2187.
 
The system will become rich if a fuel injector is supplying too much fuel - P0172 or P2188.
 
Review the Freeze Frame/Failure Records with a scan tool.
