91 non turbo. Code is 09
From what i can see that is water thermo sensor. I just replaced the thermo sensor with mazda OEM to get rid of this code. What else could it be. Yes i disconnected the battery.

Check for continuity or shorts in the wire from the sensor to the ECU. Check voltage at pin 2E of the ECU according to the factory service manual.

check the connector too. I know a few instances where a pin backed out causing an open circuit.

FerociousP, you are awesome. It was the connector, the pin backed way out. Now she starts in like 2 seconds instead of 25 seconds. And NO CODES, horay. Thanks for the quick responses everyone. Now on to titling it and registering it
