P0135 is O2 sensor 1/1 heater performance
P0155 is O2 sensor 2/1 heater performance
1/1 is bank 1/sensor 1 (driver side closest to exhaust manifold)
2/1 is bank 2/sensor 1 (passenger side closest to exhaust manifold)
It means the engine is running and heater duty cycle greater than 0%. In other words, once the O2 sensors are up to temperature, which should happen within 30 seconds of engine start, the heaters in the sensors should not be turning on.
The engine computer thinks the sensor heaters are on when they shouldn't be.

JasonB, what causes them to fool the computer into thinking they are running?
Mine will not register the two codes if I fire it up and drive it. If I warm it up for even a few seconds I get the codes P0135 and P0155. TIA
