2001 Toyota Tundra P0171

I have three Toyota right now.

2001 toyota tundra p0171. The MC was replaced with an aftermarket part in January 2014. Good on you for adding to the. - The amount of mixture ratio compensation is too small.

Hi Larry my 2006 Tundra V6 is showing P0171 AND P0174 codes. If there are no intake leaks the next step is to replace the air filter and clean the airflow meter. Below are some details- 2005 2007 Avalon 2007 2008 Toyota Camry with the 2GR-FE 35l V6 24-valve engine On these applications poorly designed.

- Fuel injection system does not operate properly. Will post results when completed. The Jack S.

The technician was a nice guy and he explained to me that the service manual lists a number of things but based on his experience he would narrow it down to AF sensors. Luckily my friend had an OBD II codes that came up were P0171 P0174 system too lean bank 1 2 or something like that. While a simple cleaning of the MAF sensor will resolve code P0171 on a Toyota application in many if not most instances of code P0171 on the listed engines other remedies is often much more time consuming difficult and costly.

I arrived to a 2000 Toyota Tundra 34 running rough with a P0171 that was cleared by the shop. Now they are hearing an air leak by the Master Cylinder and Brake Booster but are not sure if the MC is the issue or the BB. I had them change the oil and spark plugs while they had.

Then it suddenly died and wouldnt restart. I am going to try and test the MAF per the method above. The cost of diagnosing the P0171 TOYOTA code is 10 hour of labor.
