service engine light on on 2001 Buick LeSabre

trouble code indicates crank pos. sensor which has been replaced what else?

anything we say will be a guess. a code never identifies a bad part, just a failed system

it could be the harness, connectors, module, reluctor wheel among some things. thats why you pay for a real diag from a real shop. they will pin point the issue and give you a bid without throwing parts at it.

Agree with Roy, diagnose the problem and confirm parts are bad before replacing them.
There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
