- 1) CHECK FOR CURRENT DTC Turn the ignition on. With the scan tool, read PCM DTCs. Is this DTC present? Yes For complete diagnosis of this DTC, refer to «P0120-ELECTRONIC THROTTLE CONTROL MOTOR PERFORMANCE»(/chrysler/crossfire/i-final-2008-2008/remont/testing-diagnostics/#dtcs-p0033-to-p0132) . No Go to 2) .
- 2) INTERMITTENT WIRING AND CONNECTORS The conditions necessary to set this DTC are not present at this time. NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal connections can set DTCs. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the wires while checking for shorts and open circuits. NOTE: Check for any Technical Service Bulletins that may apply. Were there any problems found? Yes Repair as necessary. Perform «POWERTRAIN VERIFICATION TEST - VER 2»(/chrysler/crossfire/i-final-2008-2008/remont/testing-diagnostics/#dtcs-p1999-to-p2561-checking-fuel-delivery-hard-start-engine-cranks-but-does-not-start-powertrain-verification-tests__powertrain-verification-test-ver-2) . No The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for a possible intermittent condition.
