P0125 TOYOTA - Insufficient Coolant Temperature for Closed Loop Fuel Control

Possible causes- Low engine coolant level
- Leaking or stuck open thermostat
- Faulty Engine Coolant Temperature (ECT) sensor
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection

The following is from a Haynes manual for 1993-1996 toyota corolla and geo prism:

Code 14: ignition signal. No ignition signal to the ECM. Check igniter or circuit, ignition coil, ig. switch or circuit, ECM (engine control module or "computer")

Code 24: intake air temperature sensor. Open or short in the intake air temperature sensor circuit. Check intake air temp. sensor or wiring to ECM.

It's in the engine compartment on top of the driver's side fender well. At least that's where the Toyota fuse boxes that I've worked with are.

Coolant temperature sensor may not have been replaced, or the sensor itself and/or some of the wiring may have been damaged when the repair job was done.

On this model the IAT intake air temp sensor is inside the mass air flow sensor. Also called air flow meter.

Probably on the firewall. It's a small black device with 2 small hoses going to it. About the size of a small box of wooden matches.

hey, torque must be done in 3 steps:
1st 22 ft lbs
2nd 43 ft lbs
final 47 ft lbs
use this sequence of tightening:

9 - 3 -1 -6 -8
7 - 5 - 2 -4 - 10
