2002 ford ranger - Where is the 4x4 actuator located


On the transfer case
Transfer Case - Electronic Shift
The four-wheel drive electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4WD HIGH, and 4WD LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators: one for 4WD HIGH which appears as 4WD, and one for 4WD LOW, which appears as 4WD LOW. Shifts into 4WD HIGH can be made at any speed. When shifting into 4WD HIGH with the vehicle stationary, tooth blockage may occur preventing shift completion. When the vehicle is driven above 8 km/h (5 mph) the shift will complete. When shifting in or out of 4WD LOW, the four-wheel drive (4WD) control module requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission be in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission).
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4WD HIGH, 4WD LOW, and 2WD range positions.
The four-wheel drive (4WD) control module controls the gearmotor encoder assembly that shifts between 4WD HIGH, 4WD LOW, and 2WD modes.

Replaced front pads on my 1999 Nissan Sentra. Brake pedal felt low.Had system flushed, bled and rear shoes adjusted. Still have low pedal and spongy feel. Suggestions?


have had this on different models and makes and what i do is to push brake pedal down and jam it down a length of wood or anything that holds the pedal down a bit not hard down -and leave overnight .if this fails then renew the master cylinder

Brake pedal is stiff when off and goes tt floor when running is it booster or master cylinder


Well stiff or a hard pedal when the engine is off is normal.
Pedal going to floor is a faulty master cylinder or low on fluid, or air in the lines.

I changed everything on a 2007 Chevy uplander the camshaft position sensor And the purged sensor And the throttle body and still the check engine light and the reduce engine power came back on


Reduced Engine Power Mode When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited.


?€¢
Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited.


?€¢
Throttle default mode--The ECM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position.


?€¢
Forced idle mode--The ECM will perform the following actions:


-
Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned OFF


-
Ignore the accelerator pedal input


?€¢
Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.
Did you have it checked for DTC's - diagnostic trouble code's related to the reduced engine power ?
All so has APP sensor gas pedal !
Accelerator Pedal Position (APP) Sensor
The accelerator pedal contains 2 individual accelerator pedal position (APP) sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors each with 3 circuits:
?€¢
A 5-volt reference circuit


?€¢
A low reference circuit


?€¢
A signal circuit

The APP sensors are used to determine the pedal angle. The engine control module (ECM) provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors provide the ECM with signal voltage proportional to the pedal movement. The APP sensor 1 signal voltage at rest position is less than 1 volt and increases to more than 4 volts as the pedal is actuated. The APP sensor 2 signal voltage at rest position is less than 0.6 volt and increases to more than 2 volts as the pedal is actuated.
Your best bet is take your vehicle to the dealer !

Are there vacuum hose on the brakes hydraulic system?


NO. the vacuum is used to make the brake pedal easy to push, power brakes. the pedal would be hard without vacuum, that is why the pedal gets hard with the key off and engine not running. the problem you are having is more of a hydraulic problem.
Have the brakes checked asap. the brake system may have a leak causing the pedal to go low. check the fluid level and if it is low or empty then there is a problem, could be a rotted brake line leaking or a wheel cylinder leaking.

In order for me to be able to brake the car, I have to push really hard the brake pedal, the pedal does not go all the way to the floor but I still need to push it hard. The four shoe brakes have already...


EITHER YOU STILL HAVE AIR IN BRAKE SYSTEM OR YOU HAVE FAULTY BRAKE MASTERCYLINDER.IF BRAKE PEDAL WAS GOING TO THE FLOOR FIRST OF ALL AND BRAKE FLUID WAS NOT LOW.MOST LIKELY BRAKE MASTERCYLINDER IS FAILING.

First you need to check the brakes lines and the brake pads must be replaced on your car they may be worn out........ Get it checked from the local service center........
