Why do you think there is one"? NO SYMPTOMS POSTED ! most newer cars, use the cars engine, normal thermometer called the ECT and is pure software the fan controls via relays do you need a schematic? alldata.com has it as does suzukipitstop. (google those) 3.2L --V6 engine?, always post engine, or answers will be wrong. or the 2.4L? engine? 09 GV
the fan or fans can be controls in stages, and with this magic software can even change the rules with A/C on, and does. if there are symptoms , post them. ask for TESTS. avoid Gue$$ing
ill quote the FSM now to prove my case. ECT Sensor Strategy The ECT Sensor provides a linear input signal to the Engine Control Module (ECM) for a number of engine control system calculations. The ECT signal is compared with Manifold Absolute Pressure (MAP), Mass Air Flow (MAF), Intake Air Temperature (IAT), and Fuel Trim (HO2S) in order to determine the correct air-fuel mixture for measured operating conditions. In some cases the ECT Sensor input is used in concert with the A/C Pressure (ACP) Sensor input in order to determine cooling fan and A/C system operation. end quote.
