Morning All,

I've had an engine code on my 03 accord tourer type s for some time now. Ive got and obd2 reader so have checked the codes and they have come up as:

P2A00 (My reader gave no description but a google suggests O2 sensor)
P1157 ( A/F sensor AFS line high voltage ...)
P0135 (generic O2 sensor heater malfunction(Bank 1 sensor1)

Firstly can anyone confirm that all of these codes relate to the first O2 sensor in the exhaust (pre cat) ?

Secondly, where abouts would I find this sensor on the vehcile? I thought I could get to it from the engine bay, but couldn't see it straight away. Do I need to get at it from underneath?

Thirdly, Where can I get a good replacement? Honda want over £300 for a sensor which im not willing to pay, but at the same time I'd rather not get one of the dead cheap universal parts. Can i get a good one for reasonable money? Or are they my only options?

Cheers
 
tbh i would not put on spurious o2 sensors on to that car, you may risk doing more harm than good.

best bet it to take it to a garage with full diagnostic tools and get a complete run down on what needs replacing.
 
The club does get decent discount on genuine parts from Holdcroft Honda... send a PM to a mod (i.e. Brett/Stevearcade/TypeR) for the necessary code.

If the parts from HH are still to expensive for you, then there are bound to be cheaper alternatives and/or suppliers (possibly the exact same sensors). Some Civic K20 owners swear by Tegiwa Imports for lambda sensors.

On my Toyota (3 lambda sensors!), if a sensor heater burns out (rather than the sensor element fails) then I cut the heater wires off and splice in a resistor to fool the ECU into thinking that the heater circuit is still OK... works fine and many other owners do the same thing. Two of mine are currently modified in this way. But I don't think that this would be good practice unless the primary sensor(s) is in or near the manifold... and I'm not sure where your's are.
 
You can source decent oem sensors for these cars now without issue. I found one from the USA and replaced it on my wife's car (identical sensor to the one you need) with the correct fitting plug, just last month.

It came in at less than £100 delivered including taxes.

I'm on my phone at present but just search the forum I actually posted a link to it. Search for something like ''replacement lambda' and my thread will come up.

Don't go for a cheap universal part. What I bought was a correctly matched and rated wideband sensor of equivalent oem quality with a plug and play fitting, and I did this after a lot of research and speaking to a few distributors..
