Ford Crown Victoria
On the 1997 Ford Crown Victoria, the P0141 is a fairly straight forward code pointing to a fault with the internal heater for the Oxygen Sensor for Bank1 Sensor2. The on-board computer uses this internal heater to get the sensor to normal operating temps within a matter of seconds on cold starts. When it does not see the heater respond, the code is set. Most commonly, this is simply the case of a faulty sensor, and replacement usually solves the problem. Make sure to give the electrical connector and wire harness a check for any loose, broken or damaged wires. If the visual inspection checks ok, replace the Oxygen Sensor. You can find the Sensor is located under the vehicle, mounted to the exhaust, behind the Converter on the passenger’s side. Make sure that the replacement sensor is a “direct fit” type sensor. If the replacement sensor needs to be “spliced” into the wire harness, this is a “universal” type sensor and will not solve the problem. There is also a special tool that will make this job much easier: Oxygen Sensor Socket. The socket allows the sensor to be more easily removed without the wire harness getting in the way. You can usually rent this tool from most local “big chain” part stores.
