C240 secondary air code 0410
 

[>:]Any thoughts on reoccuring 0410 code? Diaphram valves seem ok, blower seems ok. Freeze frame shows code always setting when at idle and secondary air commanded off - as if it just did a secondary air test? Long term fuel trim a little positive (7-9). 46K miles with no other code present.
