CEL codes 41 & 3

[Altecians]

Hey guys,

Got CEL codes 3 &41.

3= Manifold Absolute pressure Sensor (MAP)

41= Primary oxygen sensor heater.

I wanted to know where the best place to source these sensors would be?
genuine preferably!

Thanks!

I would not go changing both straight away as one problem could trigger two codes, if you dont have the tools to test the components I would try the map sensor first.

Thankyou for the suggestion, I'll look at the map first and see how it works out .
Do you have any suggestions on sourcing a replacement ?

I should have a map sensor home somewhere, the ECU will need to be reset I believe if you change it? I will not have the time to post tomorrow, maybe on Wednesday, it will probably cost couple pound to post. If it solves your problem you can then pay me if not just post it back. I have no clue how much these cost second hand, a fiver maybe?

Thanks oifovo, please keep me posted. I might be able to borrow one sooner than that but should it be what needs replacing I'll let you know to buy from you!
