If you have put it back to normal then try starting the car 3 times in row (and let it idle for a few seconds before shutting off the engine and starting it) if the fault has gone - it will keep a record of it in the ECU and the check engine light will go out, if this does not go out after three successfull engine starts then the fault is still there and something is faulty...
Im starting a thread as my engine coolant temp sensor brought up a fault about 6 months ago and it went away on its own, it still came up on the diagnostics reader but as a pending fault, cleared this and it had gone completly... today it came back - check engine and a triangle lit up on the dash - then coolant temp sensor fault appeared, i shut engine off and started it three times in a row and it went away, but then about an hour later it came back and has gone away again - need to change this sensor
