Question

what does P1157 code from check engine light for a 2007 Honda accord SE

Answer 1

Hi there,

The code is for the front O2 sensor showing high voltage. This is typically caused by the sensor itself. It shorts internally and causes the code. It is also possible there is a wiring issue, but in most cases the sensor is the problem. This is the one located in the exhaust manifold before the catalytic converter.
