This means an open circuit inside the sensor and it has to be re- placed

hey if you truely think it is your egr valve unhook it and if that is the problem then when it is unhooked it should run better and the codes should not come up. hey if you cahnged the 1 o2 sensor and not the other you probably made the code for the one u repalced come up again. i would recommened that you change both of the o2 sensors at the same time. try checking if your catalatic convert is plugged. how you do this is take a dollar bill and hold it at the end of your tail pipe while it is idleing and if the dollar bill stays still you have a plugged catalatic converter.

SOURCE: Code P0141. O2 Sensor heater circuit fault (Bank1,

It is probably the sensor before the cat. if it has a heater. The heater circuit going bad is a common problem, it does not affect the way the car runs after it warms up, it is an emission device to heat the O2 sensor up quicker than the hot exhaust gas would. It should be replaced because it will keep your check engine light on and you would not be able to pass an emission test.

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

P1130 CODE FOR 2000 TOYOTA SIENNA


The air/fuel ratio sensor has gone bad (basically the O2 sensor). The code P1130 is Bank 1 Sensor 1.
Sensor 1 is before the catalytic converter coming off the exhaust manifold. Bank 1 is which ever side cylinder 1 is on your engine. In this case its a sideways engine and its closest to the firewall.

CODE P1130 ON TOYOTA CAMRY V6 YEAR 1999


Sounds like there is an issue with the heater on the bank 1 sensor 1 O2 sensor. Bank one is the same side of the engine as the number one cylinder and sensor one is always before the catalytic converter. Check for battery voltage on the black with yellow wire with the key on. There should be twelve volts. Check the heater circuit of the O2 sensor with an ohm meter. Unplug the O2 sensor connector and measure resistance on the sensor side of the connector that the blue with black and black with yellow wire go to. Off the top of my head it should be around 14 ohms. You can confirm this by checking the heater circuit on the bank 2 O2 sensor. If there is voltage and the heater circuit doesn't ohm out than replace the O2 sensor. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Failed inspection! Check engine light on and received codes po440 and p1130 on a 2001 subaru impreza What could this possibly be?


your p1130 code is Oxygen sensor circuit malfunction (Open circuit) and your p0440 is Evaporative Emission System. so you could have a bad o2 sensor or a disconnected wire connector, sometimes with the heat they go bad after awhile check your wires and your sensor for continuity. For the EES it could just be your fuel cap is bad or not on tight enough, i keep getting this one too because i don't make it tight enough after fueling. good luck

What is diagnostic procedures for DTC p0135 & p0141


Oxygen Sensor problems... P0135 (Bank 1, Sensor 1) and P0141 (Bank 1, Sensor 2)

P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it.

The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

Symptoms: You will likely notice poor fuel economy the illumination of the MIL.

Causes: A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

Possible Solutions:
Repair short or open or high resistance in wiring harness or harness connectors
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)



P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141.

Symptoms: You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Repair short or open or high resistance in wiring harness or harness connectors


Hope this helps (remember to rate this answer)..

Code p1130 p1135 p1150 what are this ??? Thanks


p1130= bank one sensor one, Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (sensor is located underneath near the firewall) p1150= bank two sensor one, Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Directly behind the radiator) p1135=bank one sensor one, Air/Fuel Ratio Sensor Heater Circuit Malfunction Bank one sensor one sensors run around $206 Bank two sensor one sensors run around $150
basically its o2 sensors if your mechanically inclined its a good weekend job to tackle yourself and safe a couple hundred dollars in labour, you would need to invest in an o2 socket and some pbblaster penetrating lubricant to get them out..hope this helps you and dont forget to rate if it does help thanks

Air/flow senor #1 bank made the check engine light come and the code is p1130


P1130 = Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 1).

Chances are the upstream sensor (similar to an O2 Sensor but not compatible) is shot. However, before condemning the sensor, check the circuit (wiring, connector, etc.) for power, ground, etc. If you can, check fuel trims as well.

If it is the sensor, take your VIN# to the dealership for an exact replacement. Be advised...they don't give 'em away.

Good luck and keep us posted.

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.

Thankyou for use fixya...
