[QUOTE="DILLARD000, post: 1051087, member: 74901"] 1st thing I'd look for is a blown Fuse for the OxSensors; check your 2002 owners manual; this one should be in the FuseBox under hood; pull the fuse & use an OhmMeter, not just a visual check. 2nd thing, assuming your OBD2 Scanner+Software can display live data, what are the OxSensors\MAFSensor\TPSensor\... signals doing, both during start up & after engin has warmed up. 3rd, do an eyeball inspection on the OxSensors\MAFSensor\TPSensor\... & Cabling; look for loose\disconnected plugs or frayed\damaged\burned\broken wiring. OxSensor cables commonly get too close to exhaust manifolds\pipes & melt. 4th, the TPSensor is just a 3pin variable\rotary resistor, notorious for getting dead spots; remove the TPS, use an OhmMeter to check that resistance varies smoothly as you rotate the shaft. Hope this helps. [/QUOTE]
