I have a 06 Prado 4 Litre Petrol all been good apart from ongoing Fault Codes It has done about 77.000 km mainly country and towing
The check engine light is on very few days
Code is 420 Cat Efficiency it seems to occur under light throttle (more when inlet temp lower (leass than 15 deg cel) it spent about a week at a dealer and they seemed to replace all and it worked for a few days then back again and so far that bank. Bank 2 has been fine now for several months now bank One is showing the same
The figures are always close to these:
Revs 2800 Air temp 6 - 16 Throttle position 25% Speed 90 - 100 kph
In conjunction with the light being on I get worse fuel consumption about 15 - 20%
Can anyone help??? Toyota just keep saying bring it in and we will reset it and download the freeze frames
Thank You
