P0135- O2 sensor heater circuit malfunction-Bank 1 Sensor 1
P0136- O2 sensor circuit malfunction-Bank 1 Sensor 2
P0141- O2 sensor heater circuit malfunction-Bank 1 Sensor 2
P0155- O2 sensor heater circuit malfunction-Bank 2 Sensor 1
P0161- O2 sensor circuit malfunction-Bank 2 Sensor 2
THEN: there were the same exact 5 codes that are listed above but there was a "Pd" after it.
What is "Pd" ?
Are all of the 10 codes basically just telling me to replace oxygen sensors 1 and 2 on banks 1 and 2?
Any ideas would be great. Thanks =)
