Check engine light

no car told, maker,,model,year. (or country)
what is gripe (Errors DTC)?Diagnostic trouble codes.?
loosing ETC or ECT? , the engine overheats or under heats?
ECT is sensor that shows engine temperatures.
"engine Coolant temp"
the front 02 sensor bank 1 is dead.(heater) or wires to it bad.


on 4 cylinder engine B1S1 is just front sensor ,in front of the CAT
on V6/8 engines it is bank 1 front
bank 1 , B1` is cylinder bank with #1 cylinder present.
S1 means front S2 means rear of CAT..

This video may help you.

3.0L V6

Sienna
wild guess, the 1MZ engine?



141 fed code is. (it means B1S2 heater is bad,or wire to it cut or shorted.) below is fSM spec. worsd.





HO2S-12 (Bank 1 Sensor 2) Heater Circuit Malfunction








Number of Trips to Set Code: 2

Trouble Code Conditions:

Engine started, engine running, and the PCM detected the HO2S-12 heater current exceeded 2 amps, or that it was 0.25 amps or less.

Possible Causes:

• * HO2S heater control circuit is open, shorted to ground or power



• * HO2S heater power circuit is open (check power from the relay)



• * HO2S heater is damaged or has failed



• * PCM has failed

then the factory code p1135 same deal,same reasons B1S1





A/F Sensor-11 (Bank 1 Sensor 1) Heater Circuit Malfunction








Number of Trips to Set Code: 2

Trouble Code Conditions:

Engine started, engine running, and the PCM detected the A/F Sensor-11 (A/FS-11) heater current was less than 0.25A, or that it was more than 8.0A at anytime during the CCM test.

Possible Causes:

• * A/F sensor heater circuit or ground circuit is open



• * A/F sensor heater power circuit is open



• * A/F sensor heater is damaged or has failed



• * PCM has failed

bar stool answer.

both bank 1 senors (oxygen) are bad. if wires are good.



easy answer ,no?



the PCM never lies. the current IS ILLEGAL,(BAD)

the why takes , inspection and ohms checks , FSM shows this..



your next question is where is bank 1,

its on cylinder 1 side.

your next question is , where is cylinder 1,

it the cylinder that sticks out further to crank front pulley.



front 134

front 246

Trouble Code: P0032

O2 (B1 S1) Heater Circuit High

Possible Causes:


O2 heater element is damaged or the heater has failed.O2 heater control circuit is open or it is shorted to power.O2 heater ground circuit is open.PCM has failed .Hi Suzanne,here's a link to your firing order,your oxygen sensor in cylinder one,which is the exhaust manifold is bad.Need more help,I'm here.I took a guess at your engine size,if I'm wrong let me know and I will send you the right one.

Code P1135 is a vehicle specific code for selected Toyota vehicles - it really helps to know what car you are working on...Year, Make, Model, Engine Size, Automatic or Manual Transmission, etc. There may be Technical Service Bulletins that apply to your vehicle that cover things like reprogramming the engine controller to correct this code, etc. Nobody can give you that information if they don't know what kind of vehicle we are talking about.

In general, the code description for code P1135 is "Air Fuel Ratio Sensor Circuit (California Emissions )"
The possible causes are
1. Open or shorted Air Fuel Ratio Sensor (AF) circuit
2. Faulty AF sensor
3 AF sensor heater or heater circuit shorted or open
4. Engine Control Module (ECM) Fault

The Mass Airflow Sensor (MAF) cannot cause this code - this is a "CIRCUIT" code, not a not a "LEAN" or "RICH" Oxygen Sensor (or AF Sensor) code. The MAF can only cause lean or rich codes.

Most of the time, this code is caused by the sensor itself, however, as I mentioned earlier, there are Technical Service Bulletins for several Toyotas that involve reprogramming of the Engine Computer.

Not sure where you got that definition for that code but this is what it is and means with possible causes for whichever motor you have:
