Q: My engine fan runs constantly and I have P0117 — is it the connector?
A: P0117 (ECT circuit low) causes the ECU to assume the engine is overheating and run the cooling fan continuously. A corroded ECT connector is a common cause before the sensor itself fails. Inspect the connector before replacing the ECT sensor.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
