P0133 trouble code

Fix code P0133 trouble code A P0133 trouble code Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1) to changes in fuel delivery. This sensor is located on the engine bank that houses #1 cylinder and is located BEFORE the catalytic converter The PCM sends a reference voltage (usually 5-volts) to the variable resistor in the oxygen sensor and looks for a return voltage. It expects to see a rapidly changing return voltage varying from .1-volts to .95-volts. If the voltage doesn’t switch rapidly, the PCM will set a trouble … Read More

These lean codes can be set by a MAF that has a contaminated or damaged hot film element. When that happens, the MAF sensor doesn’t send the correct air density/volume information to the PCM and it cannot calculate the proper amount … Read More

P0133

Fix code P0133 – Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1) A P0133 trouble code means the oxygen sensor response doesn’t meet proper criteria. An Oxygen sensor must switch constantly between .27 and .62 volts. The engine computer waits until the engine has reached at least 145 degrees and the vehicle has driven at least 10MPH for 30 seconds before it starts looking at the switching rate. The computer looks for about 8 voltage changes per second (these are called CROSS COUNTS). If it sees less than that, … Read More
