Need some help troubleshooting why my fan won't turn on. 2003 with a 2.4L engine. Getting error code P1491. A/C was removed by PO. I run the engine until 210F and the fan does not kick in. Here is what I have done so far.
- I have replaced both the coolant temperature sensor and the fan relay.
- If I jumper pins 1 & 2 on the relay connector, the fan comes on. So I know the fan is working and the circuit is good downstream from the relay.
- If I jumper the coolant temperature sensor, the fan does not come on.
- I am getting 12 volts at run position on in 1 of the fan relay connector.
