@Liverpool4eva873 hi brother,

even i had the same problem with my car, 3 warning lights are showing always on. but its not a big problem. because mine is showing since 6 months. and what you have to check just speed ur car 100/kmh and apply the brake and make sure your ABS is working. if its working just fine. and you can check with your rear wheel speed sensor both sides. even you can own a code OBDII code reader. it will tell you exactly which sensor is wrong. but my case is falty ABS unit.

my car always show abs light flashing, what could be the reason for that?

[ktharis]

@deepu894  hi just check with your alternator voltage.....tell me the car model. so i will tell you how u can check ti yourself....

hi guys thanks for the comments. i have fixed the problem is faulty "voltage Regulator" from Alternator. but i have replaced the alternator with new one because my old one was running with bad bearing. any how the car is running perfectly. guys remember when you have such a trouble, just repair it quick because over voltage will damage your sensors....

Hmmm........ P1055 = VVT - Voltage Supply Cointrol Motor, High Input(Bank1)

Check alternator and battery. The flashing lights are probably due to the irregular voltage.

@DiarmaidGNR hi thanks for your comments, i am going to change the alternator today. i will post the result soon.

it could be the harness behind the dash also you can do this test get a heater and put under the dash before you start the car pre heat the dash see if the problem exiest thanks

This warning means your acid battery of your select's battery is too high voltage,change the lower vlotage battery or it may broke,when repair,you will maybe in deep shit...
