repalced o2 sensor 1 and still getting p1157

Question

got P1157 code from scanner, bought a o2 sensor for Autozone, Bosch, installed and I am still getting the code back, what next, 2003 honda accord ex.

Answer 1

P1157 A/F Sensor (sensor 1) AFS line voltage high

When there is line voltage high there is either no connection or no continunity which allow the voltage to go low when the A/F is working properly.This can be from a poor A/F harness mating connection. The use of aftermarket sensor are also a known cause for this code condition.
