macdaddy2012 Posted June 20, 2023 Share Posted June 20, 2023 Hello all, I'm running into an intermittent engine stall when changing from park-drive-reverse-neutral on my 06 scion xa with the 1.5L 1nz-fe. Engine does not stall when at speed, idle isn't terribly rough, about 750rpm in Park, ~650rpm in R/N/D. It'll drop rpms occasionally down to maybe ~550rpm and get a little rough but this is pretty slight. No engine misfires recorded. Check Engine Code P0355 "Engine Control Circuit Crankshaft Position (CKP) Sensor - sensor circuit malfunction". Actions Taken: Replaced CKP Checked resistance of old and new CKP per shop manual page ES-186 (985-1600ohm acceptable range). Both were within range. Issue persists on new sensor. Checked resistance/ continuity/ shorts from + and - terminals of CKP wire harness to ECM Connector on the ECU. 0ohm resistance in the circuit, good continuity, and no shorts to ground detected on any of the 4 pins (per shop manual page ES-186). No visible damage to any of the wiring harnesses/ connectors. Battery is <6mo old, starts strong, no corrosion on terminals, 12v when off, 13.6v when running, doesn't seem to be a battery issue. There was some oil on the old sensor, not sure if that's normal or not. It didn't seem damaged. Does anyone have any next steps? Would love to avoid paying an expensive diagnostic fee to a shop if I can help it. Thanks all! Quote Link to comment Share on other sites More sharing options...
macdaddy2012 Posted June 20, 2023 Author Share Posted June 20, 2023 For accuracy, I mistyped the code. P0335 NOT P0355. Quote Link to comment Share on other sites More sharing options...
macdaddy2012 Posted June 30, 2023 Author Share Posted June 30, 2023 Looks like the issue was a shorted cruise control module of all things. Quote Link to comment Share on other sites More sharing options...
