My light came on, took it too a local garage as I had no loss of power or anything. codes P0037 P1532 P2503 what do these mean
P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2) (One of your oxygen sensor heaters is failing)
P1532 IMCC B: Circuit Malfunction (This is a code related to one of the two intake tuning valves (the bottom one) either the valve or the wiring could be at fault
P2503 Charging System Voltage Low
I'd get that checked to see which of these codes are currently "active" or still happening. Some of these might be inactive and I wouldn't worry about them until they come active again (if they ever do)
Except for the P2503, which could indicate a failing battery or alternator, and could eventually leave you stranded, the other two codes are pretty harmless in themselves. The oxygen sensor heater is used when the exhaust system is cold to fine tune the air/fuel ratio in the engine, and the intake tuning valves are pretty much used for the same reason (air/fuel ratio fine tuning). The worst case scenario for those is a lack of power and/or fuel economy...
