How get to P0755 fault Jaguar shift solenoid .


that fault code relates to a internal component failure inside the gearbox, or a wiring problem from the powertrain controle module to the gearbox, it all depends on the gearbox that is fitted. if the gearbox has a plastic sump pan the controle module is part of the gearbox, the shift solenoid moves a valve inside the gearbox to direct fluid pressure to the relevant servos to control gearchanges e.t.c.does the car still drive?

Accessing the Integrated Diagnostic System:

Procedure for Automatic Temp Control (ATC) equipped vehicles:

With the engine ON and the vehicle stopped set the temp to 75*F. Next hold down the Floor, Mix and Defrost buttons until the ATC display begins to flash. While the display is flashing, the system will run it's tests and calibrations.

When the display stops flashing, the tests and calibrations are complete.

The ATC display can only display one error code at a time. Any stored codes can be scrolled through by pressing the Panel mode button once for each code. DO NOT press any other button or you will have to start the test over. Note the codes and refer to the list below to determine what system is malfunctioning.

List of Climate Control DTCs:
23: Blend door actuator feedback failure (bad servo)
24: Mode door actuator feedback failure (bad servo)
25: Ambient temp sensor failure
26: ATC In Car thermister failure (ATC only, bad ATC head or ATC head disconnected while battery is connected)
27: ATC in car sensor failure (ATC only)

1998 saturn st wagon . engine code 0449


Computer is not getting current through the purge valve/solenoid. Check connection to valve. If good, you can either test the valve to see if it's bad (requires special equipment) or just replace the valve. Instructions for both are pasted below. The cost of the part is $40. Let me know if you have more questions.


COMPONENT TESTING Carefully check for cracks or leaks in the vacuum lines or in the canister itself. The lines and fittings can be reached without removing the canister. Cracks or leaks in the system may cause poor idle, stalling, poor driveability, fuel loss or a fuel vapor odor.
Vapor odor and fuel loss may also be caused by: fuel leaking from the lines, tank or injectors, loose, disconnected or kinked lines, or an improperly seated air cleaner and gasket.
If the system passes the visual inspection and a problem is still suspected, proceed as follows:

  1. With the ignition switch in the OFF position, unplug the electrical connector from the canister purge solenoid. Use an ohmmeter to check the solenoid coil resistance; it should be 19-31 ohms.
  2. Turn the ignition switch ON then, disconnect the vacuum line from the intake manifold and connect a hand vacuum pump to the valve.
  3. Apply a vacuum of about 10 in. Hg (34 kPa) to the hose and solenoid, then observe if the valve holds the vacuum. If the valve does not hold, apply vacuum directly to the solenoid to determine if the solenoid or hose is at fault, then replace the component which allowed vacuum to release.
  4. If the vacuum holds in the initial test, jumper the test terminals on the ALDL (terminals A and B are the test terminals and are the two uppermost right terminals of the ALDL connector), and observe if the valve activates, releasing the vacuum. If the valve does not activate and release the vacuum, replace the solenoid.


REMOVAL & INSTALLATION
Canister Purge Solenoid Valve
See Figure 2
The purge solenoid valve is mounted on the engine, towards the rear and below the intake manifold.

  1. As an added safety precaution, you may wish to disable the air bag(s), if equipped. refer to Chassis Electrical for the air bag disabling procedure.
  2. Disconnect the negative battery cable.
  3. Remove the air cleaner/intake tube assembly.
For DOHC engines, the solenoid can be reached through the access hole located next to the intake manifold support bracket.
  1. Unplug the solenoid vacuum hoses and electrical connector.
  2. Remove the attaching bolt, then remove the canister purge solenoid.

To install:
  1. Install the solenoid and tighten the retaining bolt to 19 ft. lbs. (25 Nm).
  2. Connect the vacuum lines to the solenoid, then install and push in the electrical connector until it clicks firmly into place.
  3. Install the air cleaner/intake tube assembly.
  4. Connect the negative battery cable.
  5. If necessary, enable the air bag(s). refer to Chassis Electrical .

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.
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.

I have a renault kangoo van, an brake pedal is rock solid which effects braking does anyone know the known causes


hi from uk this sounds like you have no servo assistance with brakes? if your engine is diesel? then the vacuum pump is not providing assistance there are different methods of haw vac pump is driven? some are driven off rear of alternator/ off the rear of camshaft ? if petrol engine ? the vac is a pipe from inlet manifold connected to servo unit this pipe has also a none return valve fitted may i suggest whether diesel or petrol engine you check the hoses from pump to the servo ? also if alternator driven pump? check fanbelt? if ok then to check if pump is fault? pull out the hose /pipe from the grommet entry point on servo unit and with engine running ? you should feel vacuum if you put finger over the end ? no vac ?? you will have to check the drive coupling from alternator if diesel engine ? if you come back with more info after tests above ? may be able to advise further?

I have a cousin with a shop in Montreal and he is having a problem with a 01 bmw 740 il,so im posting for him,the power steering shuts down when pulling into a parking spot or going slow,this vehicle has...


Power steering does not seem to have any assist when at a stop. Tests/Procedures: 1. The power steering assist is speed dependent and should be quite easy when stopped/low speeds. This is controlled by a solenoid on the side of the steering gear box.

2. Check for faults in all control modules. The general module is what controls current flow through the solenoid. Clear all faults and see if power steering operation is normal.

3. At the servo, check for power and ground from the general module. If none present, check wiring back to general module connector X254, pin 9, Black/White and pin 11, Black/Red.

4. Replace solenoid as necessary.

5. Disconnecting the solenoid will remove the variable assist function, but the steering system should still have considerable assist. If it does not with the solenoid disconnected, consider hydraulic faults as the most likely cause. A failed power steering pump is much more likely than the steering gear. Potential Causes: Defective General Module
Defective Power Steering Control Solenoid
Defective Power Steering Pump
Damaged Wiring
If your cousin has access to wiring diagrams he will be greatly advantaged in diagnosing this issue Good luck

How do you replace the egr valve in a 1997 chrysler concorde lx


Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
Operation

This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses


Component and System Testing
  1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
  2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
  3. Be sure the electrical connector is firmly attached at the valve control.
  4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
  5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.
