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.

I have a 2000 Lexus rx300 with a code p1130. what is the location of the sensor causing this code ?


That code doesn't mean any sensor is defective, it can be the sensor, problems with the engine or a faulty fuel injector or the wiring or the engine control computer that triggered the fault.

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 1150 on a 1997 ford f 150 with a 4.2 motor


I will try to paste an article for you. Several sources indicate this is a Bank 2 O2 sensor problem and that it is failing to switch and adjust for the fuel mix. But as you can see, many defects can lead up to this O2 sensor Code 1150.

I would try to use a spray bottle of water and go around the Intake manifold and spray the water while the engine is running. An intake leak will draw water into the engine and change RPM.

If no success then try changing the O2 bank 2 sensor. You may need to wipe the computer and clear the Code. H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEMicon1.png NOT SWITCHING AT FUELicon1.png TRIM (RICH OR LEAN)
Diagnostic Trouble Codes (DTCs) P1131 bank 1 (Cylinder 1) and P1151 bank 2 indicate the fuel/air ratio is correcting rich for an overly lean condition. The HO2S voltage is less than 0.45 volt. DTCs P1132 bank 1 (Cylinder 1) and P1152 bank 2 indicate the fuel/air ratio is correcting lean for an overly rich condition. The HO2S voltage is greater than 0.45 volt.
DTC P1130 and P1150 indicate the fuel control system has reached maximum compensation for a lean or rich condition and the HO2S is not switching.

•HO2S-11 = DTCs P1131, P1132 and P1130
•HO2S-21 = DTCs P1151, P1152 and P1150

•Excessive fuel pressure.
•Leaking fuel injector(s).
•Leaking fuel pressure regulator.
•Low fuel pressure or running out of fuel.
•Contaminated fuel injector(s)
•Vapor recovery system

Volvo 2001 s60 t5 can't keep the ralenti rpm at less than 1500rpm, the car constantly shut off.


code po172 is your bank 1 o2 sensor and code po121 is your throttle posit sensor that controls your RPMs .code po102 is your maf -mass air flow sensor. and code 01172 is a throw in code from the others cause problem. you need a o2 sensor and mass air flow sensor and throttle position senor

Air sensor check engine light


Ok as a guess that you have a SUV and you have different air faults. if you are a DYI'er go to an auto parts store and get an error code tool. Harbor freight for $30-50. Hook it to the car and find out which sensor is it calling for. Note, you can reset the check engine light on most tools that are not the cheapest.

2000 RX 300. Code P1130. I have already replaced the mass air flow sensor on te top of the air intake. The missing stopped but I still have this code. I have cleared the code twice and it still comes back....


P1130 A/F Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1). Some possible trouble areas include: open or short in a/f sensor circuit, a/f sensor, air induction system (which it looks like you already checked), fuel pressure, fuel injectors, or your ECM (Engine control Module). I can send you steps to check these but i need your email address cause i can not post them on the internet do to copy right laws.
