参考如下（O2 sensor，bank 1 sensor 1； bank 2 sensor 2... 插口不同，要比较实物的形状
Code p1130 p1135 p1150 what are these ? 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 More indepth explanation of scanner codes for 98 Toyota Camry 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.
Please clean up the mass air flow sensor, or check if the sensor
Please clean up the mass air flow sensor, or check if the sensor is good. You can buy a cheap one from Amazon. I'm a specialist to fix Check Engine Light.
Use a better scanner to check the presence of pending code which will show up later, not immediately. If your scanner can support live date, check O2 sensor voltage.
O2 voltage must varies with time, cannot stuck at 0.75v
Must use live data mode to check O2 sensor voltage, if it is stuck at 0.75 volt as some of the cheap sensors do, the feedback loop will produce errors, first in the pending code, late will show up as a reported error code!
check short term fuel trim and long term fuel trim
Once you find a scanner with live data capability, read long term fuel trim and short term fuel trim as well, they varies but over time should average to 0%. If they stay in large negative or large positive more then 10%, then you need to check O2 sensor B1S1, MAF sensor and air leakage down stream from MAF. Something is cause the engine to run too lean or too rich which is very damaging over the long run.
If you already made sure B1S1 O2 sensor and MAF sensor are both ok, then air leakage between MAF and intake manifold is a big suspect, check fuel trim using live data scanner to see if the engine is running too lean or too rich caused by air leakage. Do this after engine is fully warmed up so the close loop control is running.

Your error code indicates the air fuel ratio is wrong. Only three factors affect A/F ratio, MAF sensor, upstream O2 sensor such as B1S1, and potential air leakage after MAF. Therefore I said first check MAF and O2 sensor. If O2 sensor stable at 0.75 v and not change quickly with time, that indicates a bad sensor.
据说车子走1～200哩，就可以消除，于是走了260哩，然后把code消了。灯当然也灭了。
以为弄好了，正在沾沾自喜。
谁知道过两天灯又亮了。一看code，又是P1133. 说是 Feedback Fault.
再消一次code，再次发动车子，显示是：
我的问题是：如果sensor不好，为什么消了code会出现正常的status?
如果sensor 正常，为什么 P1133 和 Check engine light 会重现？
请问各位大拿，究竟可能是什么回事呢？

买的，它的标注确实是#234-9007，所以不清楚哪里出了问题？ 如果有原厂件的编号就能排查更换的配件是否有误。
也许这两个编号之间仅仅是接线长短的差异，丰田车系对氧感确实挺挑剔。

Denso sensor 一般没问题。不过也遇到过不到三个月就不工作了的，也是日本制的。
也许你只是sensor的接头没有插好。比如：https://www.walmart.com/ip/CRC-5103-Quick-Dry-Electronic-Cleaner-11-Wt-Oz/16817418?wmlspartner=wlpa&selectedSellerId=0&wl13=2918&adid=22222222227009475209&wl0=&wl1=g&wl2=t&wl3=42535874672&wl4=pla-81197605832&wl5=9026802&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=local&wl12=16817418&veh=sem&gclid=EAIaIQobChMIyvmT3uHi5AIVEtbACh0njA-7EAQYASABEgIlh_D_BwE
清理干净后，保证插头和插座插好。不要硬插。
注意，最好先断开电池的负极，再操作。
Good luck!

我用另外一个Sensor（好的那个）来对照，发现测量结果非常接近。
也許就是接頭接觸不良了
如果你觉得值得，就继续维护。但车子老了问题就多。你这是典型的日本“好车”老了。我的MDX也是这样，老了， 鸡肋了，今年下定决心换车了。

主要是挂小孩保险
O2 sensor是否有问题比较容易判断: 排出的废气是否味道呛人。和MAF SENSOR的CHECK ENGINE 问题通常比较复杂（dealer 的水平常常不能正确诊断）：建议你做如下事情：
1。 检查所有地线 （利用电瓶12V）
2。清洗throttle body
3。 清洗一valve (connecting manifold)
You're almost there.
