2013年7月4日 · P0115 is the temperature coolant sensor. P0125 Has to do with not getting into a closed loop circuit. Auto Zone listed the cure for the code (125) as faulty temp. sensor, 2. bad thermostat or3. low on coolant. When I rewired the O2 sensor the Mil went out, no more codes, From my experience on a Toyota P0125 was a disconnected or bad O2 sensor.

2015年7月16日 · I was reading through some of your posts about the P0125 code and thought maybe you could help as I have had 5 dif mechanics unable to fix the problem. I have a 2000 Toyota Corolla and it's getting the PO125 code and also P0171.

I own a 2001 Mitsubishi Montero and I changed the transmission fluids and a day later I had the engin check light on.

P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control P0126 Insufficient Coolant Temperature for Stable Operation P0127 Intake Air Temperature Too High P0128 Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature) P0129 Barometric Pressure Too Low P0130 O2 Sensor Circuit Circuit Malfunction (Bank 1 Sensor 1)
