Both of my air fuel sensors are out on my 2001 highlander. the code read-out was P0171, P0174, P1130, and P1150. they are telling me its going to be about $640 to repair it. Is that reasonable?

The two sensors alone will cost 300-400 bucks! The good news is the sensors are both in the intake line which should be easy to get to which saves on labor. They are billing 2-3 hrs at technicians labor rates to cover changing things out.

Overall, if this is a dealer, you are doing ok.

Sometimes this is NOT a O/2 sensor issue ,,,,,If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.
The P0171 code could also be caused may be caused by one or more of the following: debris on MAF sensor causing an incorrect reading, improper oil level, low or high fuel pressure or Engine Control Temperature (ECT) Sensor reading inaccurate,,,,,

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

Welcome to FixYa. I'll be glad to help you out.

Code P-1150 indicates an Air-Fuel sensor range/performance issue.

The air fuel sensor is similar to an oxygen sensor, but it does a different job.

Without in-depth analysis on a scan tool that can read the output of the A/F sensor, it is hard to tell you exactly what is happening, but prior experience indicates that you probably need to replace the A/F sensor.

You would do well to purchase a genuine Toyota A/F sensor, as the cheaper 'aftermarket' units do not perform well; your check engine light may remain on after you replace the sensor with an aftermarket

Thanks for choosing FixYa for advice.

Code p1130 p0171


P0171- mens the MAF sensor is dirty and needs cleaned. You can get MAF cleaner at your local auto parts store. The MAF is located in the air intake just after the air filter
P1130- is more than likely a result of the previous code. It is in regard to the feul/air mixture ratio. A dirty MAF can cause this code.
Also, if you are using an aftermarket oiled air filter, it would be the cause of the P0171 code.

no such thing as a catalytic computer... there is a catalytic converter ... part of the exhaust system so they may now be "guessing" that it's an O2 sensor. take the car to autozone... they will scan the codes for free.... post the codes here tho the lads and lasses there are pretty clever and will probably tell you what the codes mean.

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms
