Default P1135

Check engine light just came on 2002 Camry 4 cylinder.\

Thanks

P1135 : A/F Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

Your oxygen sensor's heater circuit bit the dust. To verify, use an ohm
meter to check the resistance. Calif spec is about 1 ohm +/- 0.2;
non-calif about 13 ohms +/- 3. Of course, it could be the wiring or
ECM, but much less likely.

I remember reading about a bad batch of oxygen sensors on Camrys. They
take out the catalytic converters, too. There was a TSB and free
replacement of the parts. Can't remember the details. So check with the
dealer about this, you might get free parts.

Thanks John,
This is a Air / Fuel sensor. It is a four wire device and I guess replaced
the traditional oxygen sensor.I ohmed the contacts and got open circuit no
matter what two I choose.
I will search for a TSB on this.I have an extended warrenty that expires in
December.Will see if they honor it or give me some shit about not coming to
them for all my oil changes.I have been doing them myself for the last 14000
miles and dont save those Autozone receipts.
So, another interesting adventure to the dealer.

=====================
You need to be very selective in using an ohm meter on an oxygen
sensor.
With a simple unheated O2 sensor, if you check for voltage output
during operation that is OK. If you check for resistance, you will put
voltage into the sensor and cause it to fail.
With the heated O2 senor, it is OK to check for continuity in the
heater filament circuit, but not across the O2 sensor.
