P1133 refers to the air/fuel ratio sensor bank 1 sensor1 (This is the first O2 sensor in the exhaust). the code indicates that the circuit is either open, shorted, or has a poor connection. Most of the time this can be fixed simply by removing, cleaning, and reinstalling the sensor (checking the connections in the process). if after reinstalling (and having the code cleared from memory) the light comes back on you should replace the sensor.
hi the codes you have given register as the o2 sensor, if the vehicle is running ok then this is what it will be, the other things that the po171 come up with are major faults and the car would run very roughly, and in some cases not at all, the codes are saying you have a short circuit on the wiring for the o2 sensor which normally means the sensor is u/s and needs replacing ...hope this helps
miles...? P1135 Air-Fuel Sensor Heater Circuit Response. the air fuel sensor malfunction is the main problem and thats causing the code p0171. Hard to start o long cranking time to starter is gona be the first symtoms. replace upstream. (the air fuel Sensor and the oxygen sensor is the same)
there should have been a code book with the OBDII. If not take the codes to a garage near you and ask them, they might give you your answers. If not, I will bookmark this page and see if I can find my book and get back to you. RT
The 4 cylinder Camry uses a MAP sensor or Manifold Air Pressure sensor instead of a air mass flow sensor which is in the 6 cylinder model. It is located just under the top of the hood in the center of the bay closest to the windscreen. The computer is programmed to meter fuel and spark timing from manifold absolute pressure (MAP), engine temperature, air temperature, and throttle position only. The MAP sensor is responsible for the codes you are facing with.
Hi.. On your question the definition of the codes are:
P0171, System to lean ( Fuel trim)
P1130, Air / Fuel sensor circuit range ? performance malfuntion This code is exclusive california Emissions). Oxigen sensor Performance malfuntion.
The first step you need to do is Check the Oxigen ( O2 sensor)
Connections The front and the rear one.
Check the condition of the Air filter Replace if need.
Check Spark plug Replace if need.
Check Fuel condition, Replace fuel filter if need.
And Clear the Codes if averything is good.
If the code P1130 return Replace the Air fuel ratio sensor..
Ok.. I hope this help on your question. If need more info letme know.
All of these codes are for a bad A/F sensor (O2 sensor) bank # 1 sensor # 1 nothing to do with spark plug of gas cap. Replace this sensor and your code will go away.
ita a little black box with 5 wires plug, between air filter and throttle, but try to reset maybe was a momentany failure,disconnect the negative battery terminal few minutes
