Replaced O2 sensor and air filter box. Re- smoged car after repairs-passed. Customer took to Test only station failed three incomplete moitors. O2 Cat. and Evap. When I tested monitors passed. Cust took to T.O. Station turned car off then failed on monitors. Why?
Why is the monitors reseting to zero after key is turned off? on 1997 Honda Civic
