Had my check engine light read and two codes came up that were stored: P0115 (Engine coolant temperature circuit) and P0125 (Insufficient Coolant Temperature for Closed Loop Fuel Control). Within the past week I've replaced the head gasket and the water pump, so I've kind of been taking a hit in the wallet on repairs. I want to get this done, but the shop is asking for up to 200 just to look for the actual issue. I've read it could be wires that were reinstalled incorrectly or just a bad coolant temperature sensor. Anybody have any ideas? Should I test my luck until the next payday to take it into a shop or can this be a DIY-job? Anything helps, thanks.
