Ecu Error Codes

[kentao]

The information i have found tells me the faults are,

21

2, then 1

Oxygen Sensor Signal

24

2, then 4

Intake Air Temperature Sensor

25

2, then 5

Air/Fuel Ratio Lean Malfunction

What would people recommend replacing first and where is the best place to buy the parts.

Thanks

I'd replace the oxygen sensor first whilst looking to shortly after replace the intake air temp sensor, replacing both should sort the code 25

It may be worth checking the electrical connections to both sensors first. Sadly dumb computers can't tell the difference betwenn a duff component and a poor connections - nothing to loose by having a close look first - could save a few quid.

As in another post regarding O2 sensors

Please don't spend a shedload of money on O2 sensors CLICKY as you can see the before cat is just as easy to replace

I had this problem and apparently it's a fault that can be caused just by pulling away from a junction to quickly

I would say faulty connection more than faulty sensor.
