P0041 is O2 sensor reversal. Check the back 2 O2 sensors on the exhaust pipes. Is it possible someone put the connectors on the wrong sensors? Try swapping them to see if it clears the code. It may take a day or 2 for it to clear. If it doesn't clear, please rescan and get back to us with any new codes.

check all hoses going to water pump and make sure they are not leaking, if hoses are not leaking then pump is going out. need to replace asap, if car has northstar engine DO NOT GET IT HOT average cost to replace head gasket on northstar is $2300.00 plus

throttle position sensor replace it. also in rare cases the map sensor will be bad . go to a junk yard and get your replacements it wont cost near as mutch. compared to the retail stores

depending where the crack is,it may not be able to be repaired but depending where u live,, about 60-75 dollars/they will rod it out also

i would check and make sure that this sensor is clean first and then i would look into having it replaced!! Welcome to the world of caddys

The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.
