You need a new O2 sensor. There is a special slotted socket used to fit on this part for removal. Just buy the sensor first, then try slipping the socket on the part to see if it fits.

The idea of the heater is this. They want your O2 to reach maximum operating temperature sooner than later. So they install a heating element inside the part to speed heating up. When the O2 is hot, the engine RPM and fuelmix will change to a leaner setting.

You can try disconnecting and reconnecting the wire first to insure that the connector is just not dirty. But chances are it will set a lost signal Code by doing it. You need to look at a diagram online for the engine definition about which bank is bank one. Usually sensor one is the first sensor starting with the engine and sensor 2 is further downstream.

You may be able to get a chart from the autoparts store to show you the location of your troubled part. Some stores will even print a copy for you.

Please rate my info.

SOURCE: P1410, P0441 & P0773 codes in '97 Toyota Camry

P1410 - Fuel Tank Pressure System
P0441 - Evaporative Emission Control System Incorrect Purge Flow
P0773 - Shift Solenoid Electrical
P0446 - EVAP Vent Solenoid Valve Control System

Ok, above are the codes listed on your description and there respective definitions. the P0441 and the P0446, basically run parallel and they mean the same thing. Its concerning the disposal of fuel fume waste that is burned in the EVAP canister during the EVAP process. the EVAP vent solenoid valve will have to be replaced.

The P1410 can be resolved be replacing the fuel pressure regulator which is part of the fuel pump assembly. I would also make sure the gas cap is correctly screwed on and its tight and mot lose.

The P0773 is quite different than the others. this concerns the solenoid that is located in the transmission pan. the scan has detected a malfunctioning solenoid that may ****** the shifting cycle of your transmission.

The EVAP situation will fail the emission's test if not fixed but, this shift solenoid issue, although not an emission's issue, should be check and fix soon.

Please rate and god bless:)

#1 stay away from Ottozoo. #2 have a good repair shop check it out. Most likely the A/F ratio sensor (oxygen sensor) is bad. the BLACK wire is power for the heater, so if the BLACK wire has power, replace the A/F ratio sensor.

Have a Ford fusion 06 Have p0141 code I fix the oxygen sensor but the codes still comes on?


Did you replace the right one ? This code does not necessarily mean the O2 sensor is bad . The code description say O2 heater " CIRCUIT " bank 1 sensor 2 Did you check the wiring , the fuse ?
P0141 - O2 Heater Circuit (Bank 1, Sensor 2) Description: See the description for DTC P0135. Possible Causes: See the possible causes for DTC P0135. Diagnostic Aids: See the diagnostic aids for DTC P0135. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW . P0135 - O2 Heater Circuit (Bank 1, Sensor 1) Description: During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected. Possible Causes:
  • Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications
  • Short to VPWR in the harness or HO2S
  • Water in the harness connector
  • Open VPWR circuit
  • Open GND circuit
  • Low battery voltage
  • Corrosion or incorrect harness connections
  • Damaged HO2S heater
Diagnostic Aids: Check the HO2S electrical connector for damage, corrosion, and water intrusion.

Plugged in a tester and the folowing code came out p0135 02 sensor heater circuit bank please advise on location and rectification


first off ECU can never tell you what is bad, it can only tell you what tests failed.
135 test. failed.
Front sensor, left side of engine (engine not stated in post)
verbetum suz
P0135Heated OxygenSensor(HO2S)Heater Performance

a kinda dumb way to stated this Performance.

a better word would be HEATER dead,
or the heater no longer draws current is the better words.

this has 2 causes.
1: heater is dead, buy a new sensor they last 100k miles.
2: the wires to it fell off, stopping current flow, dead.
the latter issues, is a look and see it. it melted or broken wires.
http://www.fixkick.com/CEL/DTCs-1.pdf

you can read this page A80 in the FSM.
see this.?
http://www.acksfaq.com/96-FSM-v2-6E3-A-part2-pdf.htm
more that 4amps draw is a shorted O2sensor
less that .22amps is open sensor.
why? , well they all go open well before 11 years running.
or last worker, failed to put back the clamps to wires. allowing them to hit the exhaust and melt and short or open.

and this being bad wastes lots of fuel , so there is a return
on investment here.

Hi, I have a 96 Jeep Cherokee with straight 6 cyclinder engine.The check engine lights on and Itook get to be put on a machine and the codes readed P0132,P0135,P0300,P0301,and P0420. Could you tell me


p132+ an O2 sensor reading is high bank1,sensor1, p135=O2 Heater circuit is bad, bank1,sensor1.

P300= Random misfires, p301 misfire cylinder1.p302 misfire cylinder2

p420 Bank1 Catalytic converter efficiency failing

What this means is that the Bank1 O2 sensor is either bad or the wiring to it is defective. Check for heat burnthrough on wires. The misfires started randomly and now pinpoint to cylinders 1 and 2.

The Catalytic converter failing because the misfires are clogging it. This can self correct once the cylinders stop misfiring.

Which messed up first is where you start solving this. Replace the O2 sensor, it is fouled out on Bank1. The heater circuit(p135) just makes it work faster and has little effect once you are underway. But high resistence in the O2(p132) means it is coated and ineffective.

There is a problem with firing #1 and #2 sparkplug. Probably the cause for the Catalytic converter plugging. A cracked coil, plug wires, sparkplugs are some causes as well as dirty fuel injectors on those 2 cylinders.

It is a cause and effect situation where 1 part fails and damages another. You need to fix the source of the problem or you will repeat th damage.

Engine fault codes: P1684 P0135 P0456


Hi the p1684 means the battery has been disconnected within the last 50 starts, the P0135 is Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor1), you may have notived an increase in fuel consumption. and the P0456 code means evaporated emissions system -small leak detected the causes could be either A small leak in any of the EVAP hoses or fuel tank hoses, a small leak in the purge valve or vent valve or the EVAP Canister may be leaking
Hope this helps
