    I had the same problem - went to Autozone and they ran diagnostics with their handheld analyzer for free. They were able to tell me which bank and which 02 sensor, and part was $100; not trusting, I followed up with Toyota dealership diagnostics and they told me the same thing but charged me $100 for the test - duh!

    I have the same problem, but my tundra is an '02. Toyota fixed the first sensor for free and left the drivers side sensor. Now it has gone out and toyota says they no longer fix it for free because the recall expired, even though I only have 77000 miles on my truck. And it was only a year ago they fixed the other one.

I had to replace both o2 sensors on my 2002 Tundra after about 50K. Toyota recalled this problem afterwards and refunded my money. My solution to you is to not worry about which one is bad and go ahead and replace both, because I had one bad and before I could replace it the other went bad also. PS: You'll have to purchase a special socket to remove them and unless you pruchase the Toyota product ( I used O'Reilly parts), you have to cut and splice the wires with a waterproof splicing kit included with the sensors. Just follow the instructions, not a hard job.

Hi,

The light will stay on until you clear the code. The code will go away once the problem is resolved (if it's not fixed and you clear the code it will come on again right away).

Rather than go through the song and dance, just read this great article for info on P0155 - http://www.obd-codes.com/p0155 - it's Bank 2 Sensor 1. That's the sensor in front of the catalytic converter on bank 2 (the side of the engine that doesn't have cylinder #1, which in your case is the passenger side). Good luck!

SOURCE: Have 2000 Toyota Camry XLE. Check Engine light

What your asking, is how to make a malfunction light
go away from your dash, so you can forget you have a
problem & make no attempt to repair the car

Until you find & resolve active OBD2 Codes that actually set
a MIL or Check Lamp it will keep coming back

Every time you clear a code you have to run a drive cylce in
some cases to start the procees over, as you need those codes
to diagnose the issues

The codes that are there, do not tell you what to replace

Without writing a book here, just study OBD Systems online &
take the car to a repair shop

It is beyond your ability at this time to figure out

How to reset check engine light?


First replace the bank 2 sensor 1 O2 sensor. p0051 is that sensor heater circuit. These codes are always the O2 sensor, unless you see the wires are melted against the exhaust manifold. Once replaced the light will eventually go out. A code reader or scanner will turn it off.

My malfunction indicator light of my Toyota camry 2000 is blinking and the car cannot accelerate well. my mechanic seems not to understand the problem. what ca I do?


When you said "...indicator light blinking," I assume you mean "check engine" light is on. Procure a check engine code reader and download the trouble code. When you isolate which component the trouble code is talking about, ascertain its not a faulty sensor. Read the code reader instruction and look up "clear trouble code" to turn off the "check engine" light. Replace the sensor first and see if it stops sending the trouble code. If the sensor is still sending a trouble code (check engine lights up again), then replace the component which the sensor is monitoring.

The check engine light is on. The 02 Sensor doesn't work. Could the faulty sensor be the reason why my check engine light is on??


Yes if the O2 sensor is faulty it will turn the check engine light on. Most local auto parts stores have a scan tool that you can use to retrieve the codes from the engine. I would recommend getting the codes to make sure there are no additional issues to prevent the light from turning off.

WHY IS THE SERVICE ENGINE LIGHT ON IN MY SATURN??


The Check Engine light will light when the ECU stores a trouble code.
Counting the Flashes
To retrieve trouble codes, turn the ignition key to the "on" position with the engine OFF.
The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.

11 Transaxle codes present 12 Diagnostic check only 13 Oxygen sensor circuit 14 Coolant sensor/high temperature 15 Coolant sensor/low temperature 17 PCM fault - pull-up resistor 19 6X signal fault (92-95 models) 21 Throttle position sensor-voltage high 22 Throttle position sensor-voltage low 23 IAT circuit low 24 VSS circuit-no signal 25 IAT circuit-Temp out of high range 26 Quad driver output fault 32 EGR system fault 33 MAP sensor - voltage out of range high 34 MAP sensor - voltage out of range low 35 IAC - rpm out of range 41 Ignition control circuit-open or shorted 42 Bypass circuit - shorted or open 41/42 IC control circuit grounded/bypass open 43 Knock sensor circuit shorted or open 44 O2 sensor indicates lean condition 45 O2 sensor indicates rich condition 46 Power steeringpressure circit(91 models)open or shorted 49 High idle indicates vacuum leak 51 PCM memory error 53 System voltage error 55 A/D error 58 trans fluid temperature too high 59 Trans fluid temperature too low 66/67 A/C pressure sensor 81 ABS message fault 82 PCM internal communication fault

Where is "check engine" sensor?


lol
thats a new one
there is no check engine sensor.
theres lots of different sensors take tell a computer to set a code and turn on that light.
ask autozone to check the codes for you for free.
its a free service they offer.
the codes will tell you whats wrong
probably an o2 sensor.
ask them if they have it in stock.

keep me posted
thank you

Check engine light on 1998 Z3 BMW


BMW engine light

Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased.

With OBD read the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again.

Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.)

Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.
