Tip & How-To about Chevrolet Silverado 1500
2006 Chevy silverado v6
had two codes come up in my truck both indicating a problem with the tps sensor first code p0121 second code p0123 read code with centech scanner from harborfreight changed the tps sensor and the iac idle air con troll valve after clearing the codes the problem was still there . I read some forums on line kept saying poke a sowing needle and check for the proper voltages around 2 to 5 volts different for every other car so any ways went to poke the first wire and saw that the wires were resting on the valve gasket cover and i could see a copper color coming from that spot so i took off the tape on the harness and wouldn't you know the wire i saw was cut completely in half from rubbing the cover so I striped both ends of the wire about a 1/4 inch got a **** splice connector and that was my fix now my truck runs great please leave feedback love to know if i have helped.
