DTC P0116: Engine Coolant Temperature (ECT) Sensor Circuit Range/Performance Problem (2001-03 3.5RL): Notes

WARNING: This page is about a different car, the 2004 Acura 3.5RL, 2003 Acura 3.5RL, 2002 Acura 3.5RL, and 2001 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If DTC P0117 and/or P0118 are stored at the same time as P0116, troubleshoot those DTCs first, then troubleshoot P0116.

NOTE: As engine coolant temperature increases, ECT sensor resistance decreases.
