what's the cause for code p1135 for a 2000 lexus es 300

Question

If I just got my computer reprogrammed would that be the cause for code p1135

Answer 1

Hi there,

It's unlikely the reprogramming would cause this code to appear. This code is for a problem with the bank 1 sensor 1 O2 sensor. This is the first sensor on the rear exhaust manifold BEFORE the catalytic converter. Usually replacing the sensor will resolve the problem.
