I have a 02 TrailBlazer it threw a P1271 code silly me went and bought a new Accel pedal position sencer, for 2 weeks no service engine light or reduced power light, And then did it again but with a crank sencer code changed the crank sencer, and that is gone. I looked on the forum and someone said check the fan hub, I unplugged the fan cleared the codes it threw a 1481 fan code but nothing for the P1271 after 35 + miles it threw all the same lights and codes again any info would be greatly appr.

 

Did anyone send you info on how to fix the 02 Trailblazer with the P1271 code etc. Any info would be greatly appreciated. Wyoming53@msn.com
