SOURCE: Getting a PO125 code in my 98 Camry (4cyl),

Same as Solution #2: The coolant temperature sensor looks like a plug (or butterfly plug) that just screws into the lower portion of the radiator (facing engine bay).

All you need to do is to unplug the electrical wire, loosen the existing one, replace quickly with the new one, this way you don't have to drain your coolant again. But do this when your coolant is not hot to touch.

SOURCE: '01 Sequoia throwing 2 OBD II codes: po125

DTC P0125 OBD-II - Insufficient Coolant Temperature For Closed Loop Fuel Control
This means that the engine coolant temperature (ECT) sensor indicates that the engine has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine. You will likely not notice any drivability problems.

A code P0125 may mean that one or more of the following has happened:
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor

DTC P0135 OBD-II - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135. You will likely notice poor fuel economy the illumination of the MIL.

A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

For additional details, feel free to contact us in the preivous code link.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Po125sensor andpo1135locations

The two codes may be related I would tackle the PO1135 first, the code pertains to the A\F Sensor. If you have the v6 it is after the y pipe right before the catalytic converter.

2000 camry code po125 what is proper operating temperture

Or you have a faulty thermostat. The thermostat may not be allowing the engine to reach operating temperature if stuck open or leaks keeping it in open loop. This will affect fuel milage. If the wiring to the sensor is good replace the thermostat and ensure the coolant level is correct and that ther is no air in the system after servicing.

Hi can help me to fix code po125 on 2003 toyota corolla yuo know i try to fix but still came back the same code po125 , i change engine temperature coolant sensor and 02 oxyge sensor also 02 heater sensor...

Did you reset the Computer after you did the repair? After you replace a sensor that has stored a fault code you need to reset the computer in the car to clear the stored codes. Auto Zone or O'Rielley's may do it for you or try removing the Negative battery terminal for 60 secs.

1999 Camry PO125, P1130, P1135. What should I do? Dont want to more alot into it. It's my sons car at school.

Hello. Sorry to hear about your troubles.

The P-0125 DTC:
Specifically, the "coolant temperature is too low for closed loop operation", This indicates a partially stuck open thermostat; the coolant is not reaching the optimal temperature to allow the computer to use the various sensors on the engine; it is staying in a pre-programmed or defult mde.

The P1130 and the P1135 indicates a bad Air-Fuel sensor.
On a 4 cylinder, this would be the one on the exhaust manifold.

Replace the thermostat and the air/fuel sensor. Try to use Toyota parts; it has been shown that 'aftermarket' sensors do not perform very well in Toyotas. If you buy a 'generic' sensor, the code may remain, and you problm will not be fixed.

Thanks for choosing FixYa for asistance.

Check the wiring around the Oxygen sensor.
This error indicates the sensor is not sending the correct signal to the computer.
It may be wiring or the sensor itself.

Try replacing the gas tank cover. Seriously. If that does not work, it could be the clutch sensor.

If you have changed out the parts and still get the codes you probably need to have the ECM reset. The dealer can do that for you or a repair shop that has the scan tool.

Oxygen sensor 2000 galant

The first sensor closest to the exhaust manifold is for the air to fuel ratio. The second one if it has one will be further downstream and checks to see if exhaust is plugged.

Is your car running right especially at idle????
