the code only tells you where the problem is not what to replace , you need to get the definition of the code and go from there .
The dummies at the parts stores are real good at trying to sell parts based solely on trouble codes. This is a very poor and misleading practice. The code sometimes will tell you which system has the problem and sometimes not. Proper troubleshooting is always the best course of action.
