2004 1.6 Error Code 0541 - KnowNothing
My engine warning light has been on for a couple of days, although the car seems to be running fine. I read about the diagnostic test can you can run by starting the engine while holding down the mileometer - this resulted in code Er 0541. I've googled this but can't turn anything up - could anyone tell me what the code means?

Thanks.

hi
recently found this

P0541 is "Low voltage on the #1 intake air heater relay". It's set when the signal from the #1 intake air heater output does match the signal from the #1 intake air heater feedback. Possible causes are:

-Loose connection
-Intake air heater relay failed
-signal circuit open from relay to ECM
-signal circuit shorted to ground
-ECM
hope this helps
