Re: loss of engine power
these codes are the heater circuits for the down stream O2 sensors. check the wiring at these for improper routing melting on the exhaust chaffing or some one hacked up the wiring by installing a generic O2 sensor that caused a wiring failure. the fuses must be checked should be called O2 B 15 A.... I say the wiring because if the fuse is blown this is usually why. if the sensor wiring on these is messed up buy new @ amazon denso O2 sensors these are the OEM and are about 50 USD...
