The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. ­Th­e oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. As soon as I connect the O2 relay the input power for the coil disappears, thus the relay is unable to function without the coil. Oxygen Sensor by Bosch®. Bank 1 refers to the side of the engine that has the #1 cylinder. So there’s an extra wire or two going to that type of sensor, for the heater circuit. There are other possibilities besides bad sensors that will set these kinds of trouble codes. 12–volt feed circuit for the sensor heating element; a. Since you did a transmission swap and it worked for a few miles before blowing, check the wires going to the O2 sensor. Some engines rely on a signal from the IAT sensor to initiate the cold start injector program. The right front oxygen sensor is located on bank 1 and before the catalytic converter. The oxygen sensor measures the amount of oxygen in the exhaust, telling the computer whether there is too much or too little fuel being injected. If one of the following vehicles comes into the shop with the “Malfunction Indicator Lamp” (MIL) “ON” and one or more of the following Diagnostic Trouble Codes (DTCs) are stored in Engine Control Module (ECM), the repair may be as simple as installing an additional ground sub-harness. Seems like it shows up every few months, I clear it and it goes away. The other thing I noticed (and was curious about) is the O2 heater function, there are reports of premature O2 sensor failure with certain down pipes, and the theory is that having the sensor further down stream causes the heater to run all the time and that causes early sensor failure. The CAT cleans up the rear OXS by exothermic reaction and when the amplitude drop isn't seen between the forward and rear OXS you get stupid problems with spacers. Note: Due to the limited preconditions provided with this drive trace, NCVECS recommends using the monitor specific drive traces for Chrysler vehicles. P0133 is a diagnostic trouble code (DTC) for "O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)". Within each of these monitor tests are additional subtests of various components. Electrical problems that cause the sensor to short out, exposure to lead, if your car is burning oil (high oil consumption) it can contaminate the sensor causing it to fail, if your car is running rich over a period of time it can deminish or destroy the sensor, also antifreeze or oil on the outside of the sensor can harm it.
