I also got code u0122 on honda accord 09 showing abs,vsa,and brake light need help please!

Auto parts stores where I live will check the codes for free.
You can order code readers to check the codes for under 40 dollar, well that is what mine cost.
In the post below one guy disconnected the neg cable from the battery and the code cleared and did not come back.

unless you pay attention to injector problem replacing plugs will not fix the fault
run the fault codes to find out why the VSA light is on and get the codes for the misfire

Vsa and a brake job doesn't shut down the engine. Have the code read.

Vsa,abs,and brake all work off of the same sensor. You have a problem with one of the following system. Vsa vehicle stability assist, abs anti lock brakes, or the brakes themselves. My guess is either the abs or vsa

You need to have the vehicle scanned for fault codes and then the causes of those codes diagnosed.

You will need to have this car checked out by a professional with the right diagnostic equipment for Hondas. The Vehicle Stability Assist (VSA)***, brake and ABS warnings may just be due to a failed sensor or sensors but you need to have a proper diagnosis carried out so the causes can be identified and any failed parts replaced.

The flashing D light relates to the auto transmission and may well be a caused by a faulty sensor on the transmission or something else. The correct scanner should throw up any fault codes being generated. In the meantime if your Accord model has the engine bay filler tube and diptstick for the auto transmission , check your fluid level in the auto transmission.

You most likely have an ABS issue. You need to have the ABS system scanned for cods and repaired accordingly.

VSA and ABS use anti-lock brake sensors to complete the calculation.

The first thing to check is to make sure all 4 of the ABS sensors are clean.

Go to your local car wash and clean the wheels first.
KEY OFF / then reconnect the VSA sensor.

Pull the OBDII and email it to me.

you need to connect the car to a fault code reader this will tell you if an abs sensor is faulty and which wheel it is or if it is the abs unit

Please see my tip at http://www.fixya.com/cars/r6003525-abs_traction_control_lights . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

The Vehicle Stability Assist system is turned off. Vehicle Stability Assist (VSA) is an electronic stability control system that works in conjunction with the Pilot's drive-by-wire throttle and its 4-channel ABS systems to enhance controllability while the vehicle is accelerating, braking, cornering or when the driver makes a sudden maneuver. VSA functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to help the vehicle maintain the driver's intended path of travel.

You need to find the VSA button on the dash and push it, this will activat the VSA and turn off the yellow light.
