Honda Repair: speed sensor o2 sensor and mass air flow sensor, mass air flow sensor, mass air flow

Question
i have a 97 honda civic and my g/f had a wreck in it she ran into somebody and wrecked the front of the car so why is the speed sensor both o2 sensors and the mass air flow sensor out cuz i took it up to auto zone and they put it on the computer and it gave them all four codes so why did they go out for.

Answer
Jimmy, don't trust Autozone to examine your codes. Purchase a repair manual and there is instructions on how to read the codes yourself. It seems highly unlikely that all these sensors went out at the same time. But, there is a possibility it did. Inspect each plug-in at the front and rear sensors to see if they are connected properly. The VSS is towards the rear of the Trans. inspect that plug-in. You can also disconnect the Neg. (-) battery cable for 30 secs. This should reset the computer and see if the codes return?
