SOURCE: code's po171 and p0125

Bank 1 and 2 detecting too lean a condition. Yuck. Per the 1998 official Toyota shop manual for a Sienna, it could be a bad 1) coolant temp sensor 2) bad HO2S (or Fuel/Air sensors) 3) bad mass airflow sensor 4) restricted fuel somewhere (like the fuel filter in the tank! ouch.) First, check to function of the coolant temp sensor. You can pull it and play wiht your stove and boiling water or just buy a Carchip data collector and download the data to your computer to analyze. Second, before you replace that horribly expensive Mass Airflow Sensor, pull it out and *carefully* spray it clean with brake cleaner or an electronic cleaner of some sort. And do NOT touch any of the itty-***** wires inside with anything or you WILL be replacing it. Third, if you have HO2S sensors, you can check the resistance of them using an multimeter to see if they are within spec. I forget exactly but it's something low like 9-12 ohms at 68F. If you have Fuel/Air sensors instead, it's dealer diagnostic time. Fourth, if you suspect fuel pressure or fuel flow issues, I recommend dealer diagnostic time too. My best friend got severely burned (2nd and 3rd degree on 50% of his body) messing with fuel and his VW bug when we were in high school. 25 years later, he is still covered in scar tissue and will be forever.
I hope this helps you

How to repair P0125 for 2000 Mercury Mountaineer


P0125 OBD-II Trouble Code Technical Description Insufficient Coolant Temperature For Closed Loop Fuel Control What does that mean? 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. Symptoms You will likely not notice any drivability problems. Causes 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 Possible Solutions The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty ECT sensor, or a low coolant level).

My toyota engine light went on. The code reads P0125. I have changed 2 sensers already and light is still on.


That code in any toyota don't require sensor replacement, what it is is that the thermostat is not close complete or there is a small leak somewhere in your coolant system, the computer is spectating 180 or so from the moment that yo start the car to the moment that computer knows that that temp has to be reached if that don't happen because the car is loosing its temp due to a leak or a open thermostat , the computer sets p0125 unable to reach temp for close loop.

According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows:
Insufficient Coolant Temperature
for Closed Loop Fuel Control

This would seem unrelated to your original problem.

1999 toyota siena p0125


The P0125 code means Coolant Temperature Insufficient for Closed Loop Operation. The P0125 "closed loop fuel control" thing is referring about your vehicle no longer being in "warm up" mode. In warm up mode you vehicle does not rely on sensors, it just follows default values for a specific length of time to warm up the engine, then it will adjust everything according to the sensors's inputs to the computer on the vehicle.
Take care

Same error codes keep reappearing P0125, P1135,P0171and P1130


It seems this is a fuel problem from the description I get on my scanner for these codes. Is there any way I can get a more in depth explanation than just what shows on the scanner exp. (P0125 closed loop fuel insufficent coolant temp).Changing gas cap and plug wires solved nothing. P-0125 indicates that your thermostat is sticking open. The engine is not warming up enough to change from OPEN loop to CLOSED loop. P-0171 indicates that you have a dirty MASS AIR FLOW SENSOR. Replace the thermostat, and clean the MAF. Then clear the codes and drive it, and recheck for any codes.
