Honda Accord power steering method fault detection analysis

Honda Accord car ECU programmer sedan together with the continual flow hydraulic power steering technique, the method primarily consists of power steering, the steering mechanism and steering linkage components. The energy of steering device which includes power steering, power steering pumps, storage tanks, oil hoses and piping. Steering mechanism consists of a steering wheel (which includes the driver's seat airbag assembly) as well as the steering shaft. Steering

Guangzhou Honda Accord sedan using the continuous flow hydraulic power steering system, the technique mostly consists of energy steering, the steering mechanism and steering linkage parts. Energy steering device incorporates energy steering, power steering pumps, storage tanks, oil hoses and piping etc.. Steering mechanism includes a steering wheel (like the driver's seat airbag assembly) as well as the steering shaft. Steering linkage pitman arm, steering rod, shock absorbers and steering knuckle arm. The steering gear rack and pinion energy steering, steering pump rotor type.

Basic failure vas 5054a in the failure on the power steering program, steering noise and oil leakage. The basic failures contain tough steering, steering shocks, steering not functioning and steering kickback. A few of these faults may possibly be connected to energy steering, steering controls and steering linkage are associated. Brought on by the failure from the following describes the power steering device adverse, please refer for the basic failure with the vehicle steering mechanism with steering failure caused by the transmission mechanism analysis.

Initially, the general failure
(A) difficult steering
1. Failure phenomenon: Driving turn, turn the steering wheel really feel heavy effortlessly. Checking the rotational force with the steering wheel, and its value is greater than 30N.

2. Failure Evaluation
(1) Verify the oil tank is in oil, power steering pump drive belt is slipping, must confirm that no air within the program.

(2) Verify fgtech, fgtech galletto 2-master the energy steering pump pressure. Measuring the idle static hydraulic pressure manage valve and shut-off valve is totally open, the oil stress value ought to be equal to or slightly much less than 1500 kPa, otherwise it should be checked into the oil amongst the power steering and energy steering pump and return line The hose is clogged, aging or deformation. When the tubing is regular, then the steering gear rotary valve failure.

(3) when the measured energy steering pump stress is standard, within the case of your pressure manage valve and also the shutoff valve is totally closed, the measurement when idling pump unloading pressure, and its worth should be 7200 ~ 7800kPa. Unloading pressure is also low, you'll want to verify the flow manage valve and oil pump assembly.

(4) When the above checks unloading stress is typical, verify the rotation of the steering wheel towards the left and to the appropriate in the turning force, the difference in between the two need to be
