Shut truck off on route; went to restart 30 min later, truck started but red check eng. Light on & truck would shift into gear but wouldn't move. Called wrecker; wrecker showed up one hour later & needed truck pulled up to load. Started truck and red check eng. Light still on but went in gear and was able to drive to wrecker. Towed to business; checked all fluid levels, OK. Started truck up, no engine light; was able to pull a P2135 code (TPS positive sensor / switch A/B voltage correlation). Checked TPS, nothing obvious & road tested truck for 30 min & restarted, good and no light coming on. Would appreciate any suggestions/diagnostic help and especially any schematics showing circuit checks including ohm checks; don't want to replace TPS sensor without know that's the problem, thanks.
have the same problem?
