What is the prosedure to repair a 1345 code

Check fuses 20 and 21 (both 20 amp fuses) marked ENG1 and ECM1 they send power to the sensors. check for power at the pink wire at each sensor (ignition on) check for wiring damage. For actual test procedures for the sensors or wiring diagrams Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info .There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://bit.ly/alldata_repair_manuals or try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
