Toyota Previa Check engine codes P0171 P0130 P0133

SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

P0130 Oxygen Sensor Circuit Malfunction - Bank 1 Sensor 1.
P0131 Oxygen Sensor Circuit Low Voltage - Bank 1 Sensor 1.
P0132 Oxygen Sensor Circuit High Voltage - Bank 1 Sensor 1.
P0133 Oxygen Sensor Circuit Slow Response - Bank 1 Sensor 1.
P0134 Oxygen Sensor Circuit No Activity detected - Bank 1 Sensor 1.
P0135 Oxygen Sensor Heater Circuit Malfunction - Bank 1 Sensor 1

P0130 IS Oxygen Sensor Circuit Malfunction
(Bank 1 Sensor 1)
P0133 IS
Oxygen Sensor Circuit Slow Response
(Bank 1 Sensor 1)

p0133 is a slow response from the Oxygen Sensor Circut.

check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away.

Trouble Code Conditions:
DTC P0100, P0101, P0110, P0115, P0120, P0121, P0130, P0133, P0136, P0135, P0136, P0141, P0153, P0155, P0201-206, P0300, P0301-P0306, P0401, P0402 and P0441 not set, engine running in closed loop at a stable engine speed, and the PCM detected the lean or rich fuel trim correction value was more than or less than a calibrated limit in memory.

Possible Causes:

• Air leaks present in the exhaust manifold or exhaust pipes
  
• Air being drawn in from leaks in engine gaskets or other seals
  
• Base engine "mechanical" fault affecting one or more cylinders
  
• Fuel control sensor is out of calibration (i.e., ECT, IAT or MAF)
  
• Fuel delivery system supplying too much or too little fuel at idle or cruise (e.g., faulty fuel pump or dirty, restricted fuel filter)
  
• One or more fuel injectors is dirty, leaking or stuck open/closed
  
• HO2S element is contaminated, damaged or it has failed
  

Engine Code P0133 Oxygen Sensor slow to respond, replace the O2 sensor

P0133 "upstream oxygen sensor circuit slow response." Probably a bad O2 sensor.

I just came from an Autozone, and then spoke with 2 Hyundai dealership service departments and they all three stated the P0113 code is the Intake Air Temperature sensor (IAT, also referred to as the Mass Air Pressure - MAP - sensor) on the engine, not an O2 sensor found in the exhaust system.
