2007 chevy trailblazer code co131 brakes capliars locking up


DTC C0131 Antilock Brake System (ABS)/Traction Control System (TCS) Pressure Circuit

The master cylinder pressure sensor is located within the brake pressure modulator valve (BPMV). The master cylinder pressure sensor signal, to the electronic brake control module (EBCM), increases as hydraulic pressure in the front brake circuit increases.

Conditions for Setting the DTC co131
Any of the following conditions may cause the DTC to set.
• The EBCM detects open master cylinder pressure sensor circuitry.
• The EBCM detects shorted master cylinder pressure sensor circuitry.
• The master cylinder pressure sensor self-test, which occurs at power-up, fails.
• The zero-pressure signal voltage is not within an acceptable range.
• The master cylinder pressure is not within an expected tolerance based on deceleration rate and other data available to the EBCM.

My ABS light is on and off on a 2006 Mercury Mariner. Do I need to do something to get this light to stay off


SECTION 206-09: Vehicle Dynamic Systems 2006 Escape/Mariner/Escape Hybrid/Mariner Hybrid Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 03/29/2005 Anti-Lock Control adobe.gif Printable View (63 KB) The ABS consists of the following components:
  • Hydraulic control unit (HCU)
  • Anti-lock brake control module
  • Front and rear wheel speed sensors
  • Front and rear wheel speed sensor rings
  • Stability control sensor cluster
  • Stability/traction control switch
The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the HCU modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
--------------------------------------------------------------------------------------------------------------------------------------
The ABS module is self monitoring. The module will carry out a preliminary electrical check of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 20 km/h (12 mph). The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a malfunction is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

Transmission seems to shift in and out of overdrive


Check the transmission fluid level. The sensor for speed may be tripping or not tripping causing the overdrive to engage or disengage at a particular speed. ---
Understanding the Hydraulic Control System The hydraulic pressure used to operate the servos comes from the main transmission oil pump. This fluid is channeled to the various servos through the shift valves. There is generally a manual shift valve, which is operated by the transmission selector lever, and a shift valve for each up shift the transmission provides.
Most automatic transmissions are electronically controlled; electrical solenoids are used to control the hydraulic fluid. The shift solenoids are regulated by an electronic control module. Shift timing is regulated through sensor feedback information provided to the electronic controller.
On older transmissions there are two pressures that control the shift valves. One is the governor pressure which is affected by vehicle speed. The other is the modulator pressure which is affected by intake manifold vacuum or throttle position. Governor pressure rises with an increase in vehicle speed, and modulator pressure rises as the throttle is opened wider. By responding to these two pressures, the shift valves cause the up shift points to be delayed with increased throttle opening to make the best use of the engine's power output.
Older transmissions also make use of an auxiliary circuit for downshifting. This circuit may be actuated by the throttle linkage, vacuum that actuates the modulator, or by a cable or solenoid. It applies pressure to the downshift surface on the shift valve or valves.
The transmission modulator also governs the line pressure, used to actuate the servos. In this way, the clutches and bands will be actuated with a force matching the torque output of the engine.

1998 dodge dakota 5.2L V8, I have 2nd and 3rd gear only with automatic transmission.


In the 1998 Dodge Dakota 5.2L V8 if you have only 2nd and 3rd gear with the auto transmission, the solenoid inside for shifting down to 1st gear is not functioning correctly.

A complete transmission rebuild is indicated in this situation, where all of the clutches and solenoids that are bad are replaced.

This involves tearing down the transmission after removing it from the vehicle, and; rebuilding it from the ground up.

Try to find a local transmission repair shop where they are certified to do this kind of work.
----
A basic description of the problem follows:
Servos/Accumulators The servos are hydraulic pistons and cylinders. They resemble the hydraulic actuators used on many other machines, such as bulldozers. Hydraulic fluid enters the cylinder, under pressure, and forces the piston to move to engage the band or clutches.
Servo operation tccs7015.gif

The accumulators are used to cushion the engagement of the servos. The transmission fluid must pass through the accumulator on the way to the servo. The accumulator housing contains a thin piston, which is sprung away from the discharge passage of the accumulator. When fluid passes through the accumulator on the way to the servo, it must move the piston against spring pressure, and this action smoothes out the action of the servo.
Hydraulic Control System The hydraulic pressure used to operate the servos comes from the main transmission oil pump. This fluid is channeled to the various servos through the shift valves. There is generally a manual shift valve, which is operated by the transmission selector lever, and a shift valve for each up shift the transmission provides.
Most automatic transmissions are electronically controlled; electrical solenoids are used to control the hydraulic fluid. The shift solenoids are regulated by an electronic control module. Shift timing is regulated through sensor feedback information provided to the electronic controller.

My clutch is not angaging need to see how can i bleed


Hydraulic Clutch System BLEEDING The clutch system can be bled using a pressure bleeder. Follow the instructions that come with the pressure bleeder for the proper pressure bleeding procedure. The maximum line pressure while pressure bleeding must not exceed 36 psi (248 kPa). NOTE: To bleed a clutch manually requires the assistance of a second person, a section of hose that is compatible with brake fluid (preferably clear) and fits the slave cylinder bleed screw snugly and a container to catch the fluid that is bled through the system. As brake hydraulic fluid easily absorbs moisture, always use fresh fluid when bleeding a hydraulic system.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. To bleed the system perform the following:
    1. Top off the hydraulic fluid reservoir using a fluid that meets the standards of the vehicle's hydraulic system.
    2. Open the clutch slave cylinder bleed screw and press the clutch pedal to the floor and hold the pedal down.
    3. Close the clutch slave cylinder bleed screw.
    4. Release the clutch pedal.
    5. Check the hydraulic fluid level and top off as necessary.
  3. Repeat the above steps until the discharged fluid is clean and no air bubbles appear during the bleeding process.

Villager GE 95 liquid escape in a brake system


It is a brake load sensoing valve that applies more pressure to the rear brakes as you load the vehicle. It is $375 from tascafordparts.com. Get one from the junk yard or just bypass it.

usually just the lines are leaking and can be replaced.
Valve, Brake Load Sensor Proportioning The Villager has a brake load sensor proportioning valve (2B547) that is mounted on the vehicle frame and connected to the rear axle housing (4010) . When the vehicle is unloaded, the brake load sensor proportioning valve closes and partially reduces hydraulic pressure to the rear wheel cylinders (2261) . As the vehicle is loaded, the weight presses down the back end of the vehicle on the rear springs (5560) . This activates the brake load sensor proportioning valve which opens and supplies more hydraulic pressure to the rear wheel cylinders . When the vehicle is fully loaded, the brake load sensor proportioning valve is fully open and provides full hydraulic pressure to the rear wheel cylinders .

ABS light stays on sounds like a abs pump is staying on. Is there a pump for the abs system?


There is no seperate pump. The following lines will give you more details

Braking force and the tendency of the wheels to lock up are affected by a combination of factors such as the friction coefficient of the road surface, and the difference between the vehicle speed and the road wheel speed. The ABS prevents the road wheels from locking up during heavy braking by controlling the vehicle's brake system hydraulic pressure.
During normal braking, as the rotational speed of the wheel falls, no electric current flows from the ECU to the hydraulic unit. The solenoid valve is not energized. The brake master cylinder hydraulic pressure is applied to the brake unit, and the ABS is not involved. However, even though the ABS is passive during normal braking, its control module is constantly monitoring for rapid deceleration of any of the wheels.
If a wheel-speed sensor signals severe wheel deceleration - which means the wheel is likely to lock up - the ECU sends a current to the hydraulic unit. This energizes the solenoid valve. The action of the valve isolates the brake circuit from the master cylinder. This stops the braking pressure at that wheel from rising, and keeps it constant.
If the sensors signal the wheel is still decelerating too rapidly, the ECU sends a larger current to the hydraulic unit. The armature moves even further and opens the valve. It opens a passage from the brake circuit. Brake fluid is sent from the brake circuit back to the master cylinder. Pressure in the brake caliper circuit is reduced so that the wheel is braked less heavily.
If the wheel sensors indicate that lowering the brake pressure is letting the wheel accelerate again, the ECU stops sending current to the hydraulic unit and de-energizes the solenoid valve. This lets the pressure increase, so that the wheel is again decelerated.
This cycle repeats itself about four to six times per second.
It is normal in an ABS for the valves in the hydraulic control unit to keep changing position as they change the brake pressure that’s being applied. These changes in position may cause rapid pulsations to be felt through the brake pedal.
