Answer 1
TO REPLACE SENSOR IS APPROX 50.00 THATS IF THE CIRCUIT IS GOOD AND NEEDS A NEW SENSOR. WHICH SENSOR IS IT B1S1 OR B2S1? V6 OR 4 CYL? -

4 cylinder and all I know it is front sensor not the one by the catalytic converter. By the way my car has been parked for a while and battery is dead, tried to have junmp start but car alarm keeps going off, my key won't turn it off. What can I do? -
