SOURCE: dashboard warning brake light stays on continuosly nissan altima

Try this, Since you are applying the hand brake. Manually pull up on the emergency pedal and see if the light goes out. If this does work then you could have one of several problems. but, I am thinking that you might be able to adjust the brake tensioner if this car has one.

SOURCE: I want to know the meaning of error code 0077.

The error concerns the intake valve timing control solenoid (VTC). If you have the 16v transverse engine the solenoid is located on the left of the engine at the back of the cylinder head: look at the four injectors at the rear of the cylinder head and then imagine a fifth one at the left and this is the position of the VTC. If has a electrical connector to the top of it and an oil pipe connection to its side. This device is used to adjust the valve timing through oil pressure action on the cam assembly. A high reading (error code p0077) indicates that the 'ground' wire is either disconnected or broken to the VTC. Disconnect the electrical connector and ensure the the the plug pins and socket are free of oily grime or corrosion that might interfere with electrical conduction. Disconnect the negative terminal from the battery before doing such work. When everything is clean reconnect everything, clear the code and test.

Meaning of warning lights


Manufacturers spend billions of dollars a year refining their cars' on-board diagnostics systems. However, all of the sophisticated diagnostics in the world will do little good if you don't know what the warning lights mean.
Purpose
Modern automobiles have dozens of sensors to monitor engine, braking and chassis performance. Any deviation from the car's established limits will trigger a dashboard warning light.


Check Engine Light
Check engine lights can indicate failure of the emissions system, fuel injection system, faulty sensor feedback, overheating or lack of voltage, transmission failure, and engine knock ignition system failure.


Brake Lights
Almost all cars have two separate lights for the braking system: a red "ABS" (anti-lock braking system) light and "Brake Warning" light. The former indicates failure of the electronic anti-lock system, the latter a loss of fluid pressure in the brake system itself.


Dynamic Warnings
Many modern cars have traction or stability control systems that prevent and notify the driver of tire slippage. These lights can come in the form of amber "SLIP," "TC," or "TRACTION" lights (for spinning tires), or "ESC" (electronic stability control) lights for a sliding vehicle.


Safety Lights
Most cars have a diagrammatic warning that indicates a door that isn't all the way closed, a seat-belt warning light, and an "airbag disabled/enabled" light. Any or all of these will be red or amber.

What is a STFT B1(%) -1.56. WHAT DOES THAT MEAN?


Here is some general information to get you started...
(I am quoting directly from several PDF sources, Googled).

STFT B1 = Short Term Fuel Trim Bank 1. This is the fuel correction percentage being used by the closed loop fuel strategy for Bank 1 (if a V style engine or for all cylinders if an inline engine). If the fuel system is in open loop, this number will be reported as 0%

Fuel trim refers to the feedback compensation value compared against the basic injection time. Fuel trim includes short–term fuel trim and long–term fuel trim.

Short–term fuel trim is the short–term fuel compensation used to maintain the air–fuel ratio at its ideal theoretical value. The signal from the heated oxygen sensor indicates whether the air–fuel ratio is RICH or LEAN compared to the ideal theoretical value, triggering a reduction in fuel volume if the air–fuel ratio is rich, and an increase in fuel volume if it is lean.

Long–term fuel trim is overall fuel compensation carried out long–term to compensate for continual deviation of the short–term fuel trim form the central value due to individual engine differences, wear over time and changes in the usage environment.

If both the short–term fuel trim and long–term fuel trim are LEAN or RICH beyond a certain value, it is detected as a malfunction and the check engine warning (CHK ENG) lights up.

If the total of the short–term fuel trim value and long–term fuel trim value is within ± 25 %, the system is functioning normally.

An Engine Light came on the dashboard of my 2003 Ford Windstar.The code came up saying p0171 (Fuel System too lean.(Cylinder bank 1) What does this mean?


P0171=System Too Lean Bank 1,
not cylinder 1,it means the oxygen sensor on the drivers side exhaust was stuck on lean and set a code.
doesn't mean you need to change the oxygen sensor yet,first clear the code and see if it corrected its self.
