vv2006gt Posted June 20, 2015 Share Posted June 20, 2015 Hi Guys, newbie LGT owner here. Never had this problem on my 02 WRX but my new baby 06 LGT is giving me an issue. Got a CEL 21. While this CEL is on everything seems to be running fine other than CEL on and cruise control flashing disable. The temperature gauge on the dash seems to be operating ok. Any thoughts?

apexi Posted June 21, 2015 Share Posted June 21, 2015 I don't have a 2006 service manual, but I wanted to check the 2005 manual to see what it says. Usually trouble codes are 4 digits, like P0021. So I checked the FSM, and P0021 is a camshaft position error. There's also: P0117 Engine Coolant Temperature Circuit Low Input P0118 Engine Coolant Temperature Circuit High Input But those don't have a 21 in them? So I'm not sure of the exact error you're getting. Link to comment Share on other sites More sharing options...
