To start, P1135 & P1155 refer to air:fuel ratio sensors, not O2 sensors. Your 2002 Solara V6 has 2 A/F sensors and 2 O2 sensors. Did you replace the correct sensors? The A/F sensors are upstream of the respective cats in the exhaust system (the O2 sensors are downstream of the respective cats).Howdy everyone!
I just bought a 2002 Solara V6 SLE. Scanner said both o2 sensors were bad(1135 and 1155). I replaced both twice and still get same trouble codes. Someone mentioned resetting the ECM. Any ideas?
Thanks in advance
Can you give me your model code (from the sticker on your driver door area)? It should be something to the effect of MCV20L-GCPNKA. Need to have this exact model number for your vehicle. With it, I can send you a diagram of where your A/F & O2 sensors are, and what the Toyota P/N's are, which I think will help you.I just realized people were having trouble with air/fuel ratio sensors too. Code book just said sensor, not A/F or o2, so my mechanic replaced the one right on the exhaust manifold and the one downstream at the cat. He bought o2 sensors. I'll check with the parts store to see about A/F sensors. Would you happen to know location of A/F sensors? I'm assuming one is on back of motor near firewall? Thanks!
