The reading from each sensor should correspond to the equivalent data on the other sensors&mdash;otherwise, the PCM may log a P0068 code.<\/p>\n\n\n\n<p>The readings from these sensors guide the PCM when it sets how long the fuel injectors stay open and when the spark plugs trigger to ignite the resulting fuel-air mix inside the engine.
