SOURCE: 2008 Toyota Tacoma Excessive brake pedal

Your dealer is not lying to you.
All of the Toyota product line with ABS has this phenomenon. What Toyota has done is incorporate "Brake Force Distribution" into the braking system. What that means is there is now a sensor on the brake pedal/brake rod, going to the master cylinder. The sensor measures how FAST you press on the brake pedal. This activates the ABS pump, and supplies more brake fluid, harder, to reduce the time needed, such as a "panic stop"; the pedal travel is much longer than you are used to, because of the way they have to measure the speed of the rod being depressed. In actuality, this system is much better than the old system, as it also prevents wheel drag. It just takes a while to get used to. Really, there is nothing to worry about, I explain this same thing to my customers every week.

I hope this helps you out.

Thanks for choosing FixYa for assistance.

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

How do I pass emissions with my 1997 does explorer XLT P0


The recommended repair for both the P0171 and P0174 codes is to clean the MAF sensor. Ensure you use the proper cleaning solution, as there are many that will damage the sensor. Buy a cleaner that is made specifically for MAF sensors. The P0420 code will probably clear up if the MAF sensor clears the other two codes.

Ford Taurus Engine Light is: P0171 & P0174. I am thinking a MAF Sensor


Could be a problem with the MAF sensor but if it is you should have a code for that too.
Other causes include low fuel pressure, and a vac leak or air leak in the intake hose to the MAF.
The codes mean the ECM can not make the injectors rich enough to make the O2 sensors switch back and forth.

Engine check light on error code 1 is P0171 system too lean bank 1 error code 2 is P0174 system too lean bank 2


P0171 system too lean bank 1
P0174 system too lean bank 2
links to information on the codes

it means that the O2 sensors in your vehicle detected a lean condition in their respective banks. this could be caused by a dirty MAF (mass air flow) sensor or a vacuum leak downstream from the MAF sensor

sometimes you can clean the MAF with electronics cleaner or brake cleaner but be sure to take it off the vehicle first. be careful not to damage the MAF while spraying the cleaner, and allow it to dry completely before installing it on the vehicle.

P0171 and P0174 Left and Right bank lean trouble codes pulled from ECU. Check Engine Light illuminated.


P0171 = system too lean bank 1
P0174 = system too lean bank 2

The fuel/air mixture is too lean for the entire engine. The fuel pump pressure could be too low. The fuel pump pressure regulator could be at fault. There could be an air leak downstream of the MAF sensor. MAF sensor (hot wire type) could be dirty. Check for intake manifold vacuum leaks. The engine coolant temp sensor and/or the intake air temp sensor could be faulty (stuck at full hot mode).

What is engine code P0171 for 2005 Toyota corolla?


What does that mean? Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Symptoms You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.

Code p1130 p0171


P0171- mens the MAF sensor is dirty and needs cleaned. You can get MAF cleaner at your local auto parts store. The MAF is located in the air intake just after the air filter
P1130- is more than likely a result of the previous code. It is in regard to the feul/air mixture ratio. A dirty MAF can cause this code.
Also, if you are using an aftermarket oiled air filter, it would be the cause of the P0171 code.
