Hi I have an 07 V6 Accord and wondered how many o2 sensors I have and where they are located. Interested sparked by error reading.


Thanks in advance

 

Your car has two primary A/F ratio sensors and two secondary oxygen sensors.

See post # 6 in the following thread:

Thanks, that diagram illustrated locations well. I found 3 but the 4th is difficult to spot down there on the exhaust !


I'm also getting a code for the evap solenoid - I think that is inside the box just forward of the driver side rear wheel. Wish these things came in summer when warmth makes things easier.

 

What is the trouble code number?

EVAP is not related to the A/F sensors or secondary O2 sensors.

 

Yes, the code on this one is P0498.


From what I can tell from my Haynes manual I need to remove the box from the vehicle body and replace the solenoid component inside. Approx $30 component from what I've been told - guestimate by friend.

 

PS


The codes I got for the o2 sensors were P0135 and P0155. Do these refer to specific sensors on the diagram ?

 

DTC P0135 is Rear A/F sensor (Bank 1 Sensor 1) Heater Circuit Malfunction
DTC P0155 is Front A/F sensor (Bank 2 Sensor 1) Heater Circuit Malfunction

You may want to check the fuses first. All the codes may be due to a fuse or wiring.

Under-hood Fuse No. 19 (40A)
Under-dash Fuse No. 4 (15A) – protects A/F sensor relay
Under-dash Fuse No. 23 (7.5A)

DTC P0498 is EVAP Canister Vent Shut Valve Control Circuit Low Voltage

EVAP canister vent shut valve also receives power via the A/F sensor relay.
