9. Ensure throttle is fully closed and against throttle stop. Using scan tool, read TP sensor voltage. If voltage is 0.92 volt or less, go to next step. If voltage is more than 0.92 volt, check for binding throttle linkage. Repair linkage as necessary. If linkage is not binding, replace TP sensor. NOTE: The following procedure assumes that the cooling system thermostat is functioning properly. Test works best if performed on a totally cold engine (cold soak).
10. Turn ignition on. Using scan tool, read Engine Coolant Temperature (ECT) sensor value. If engine coolant temperature is more than 180°F (82°C), allow engine coolant temperature to cool down to 150°F (66°C) before proceeding. If engine coolant temperature is 150°F (66°C) or less, start engine and monitor scan tool until engine coolant temperature reaches 180°F (82°C). If ECT sensor value increases smoothly, go to next step. If ECT sensor value increase is erratic, check for cooling system problems and repair as necessary. If cooling system is okay, replace ECT sensor.
11. Check the following additional items as possible causes for start and stall condition: Check for any technical service bulletins that may apply. Fuel must be free of contamination. Engine exhaust system must be free of restrictions. Engine compression must be within specification. Engine valve timing must be within specification. Throttle body must be free of carbon build-up and dirt. If a problem is found, repair as necessary. If no problems are found, test is complete.

Note. For circuit identification and wiring diagram, see WIRING DIAGRAMS article. If Powertrain Control Module (PCM) is replaced, PCM must be reprogrammed. See PROGRAMMING . After each repair procedure has been completed, reconnect all components. Perform POWERTRAIN VERIFICATION TEST VER-5 under VERIFICATION TESTS to ensure system is functioning properly.

1. Turn ignition on. Using scan tool, check for DTCs. If no DTCs are present, go to next step. If any DTCs are present, perform appropriate diagnostic test. See SELF-DIAGNOSTICS - PT CRUISER article.
2. Turn ignition on. Using scan tool, monitor TP sensor voltage while slowly opening throttle from idle position to wide open throttle position. If voltage changes smoothly, go to next step. If voltage does not change smoothly, replace TP sensor.
3. Ensure throttle is fully closed and against throttle stop. Using scan tool, read TP sensor voltage. If voltage is 0.92 volt or less, go to next step. If voltage is more than 0.92 volt, check for binding throttle linkage. Repair linkage as necessary. If linkage is not binding, replace TP sensor.
4. Using scan tool, read and record Sentry Key Immobilizer Module (SKIM) DTC (fault) messages. If no SKIM DTC messages are present, go to next step. If any SKIM DTC messages are present, a fault exists in anti-theft system. Perform appropriate test. See appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. NOTE: If scan tool does not communicate with SKIM, repair communication problem. See BODY CONTROL MODULES - PT CRUISER article in ACCESSORIES & EQUIPMENT. NOTE: The following procedure assumes that the cooling system thermostat is functioning properly. Test works best if performed on a totally cold engine (cold soak).
5. Turn ignition on. Using scan tool, read ECT sensor value. If engine coolant temperature is more than 180°F (82°C), allow engine coolant temperature to cool down to 150°F (66°C) before proceeding. If engine coolant temperature is 150°F (66°C) or less, start engine and monitor scan tool until engine coolant temperature reaches 180°F (82°C). If ECT sensor value increases smoothly, go to next step. If ECT sensor value increase is erratic, check for cooling system problems and repair as necessary. If cooling system is okay, replace ECT sensor.
6. Turn ignition off. Visually inspect related wiring harness. Look for chafed, pierced, pinched or partially broken wires. Visually inspect related wiring harness connectors. Look for broken, bent, pushed out or corroded terminals. Refer to any technical service bulletins that may apply. Perform a wiggle test on related wiring harnesses with engine running. Using scan tool, watch for GOOD TRIP counter to change to zero. If a problem is found, repair as necessary. If no problems are found, go to next step.
7. Check the following additional items as possible causes for start and stall condition: Check for any technical service bulletins that may apply. Fuel must be free of contamination. Engine exhaust system must be free of restrictions. Engine compression must be within specification. Engine valve timing must be within specification. Throttle body must be free of carbon build-up and dirt. If a problem is found, repair as necessary. If no problems are found, go to next step. WARNING: Fuel system is under constant pressure even when ignition is off. Fuel pressure must be released before opening fuel system.
8. Turn ignition off. Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-97369-S00845111802001050300000) under FUEL SYSTEM. Connect a fuel pressure gauge to test port on fuel rail. Turn ignition on. Using scan tool, actuate ASD fuel system test. Allow fuel pressure gauge to stabilize. Stop ASD fuel system activation. Fuel pressure should be 53-63 psi (365-434 kPa). If fuel pressure is less than specified, go to next step. If fuel pressure is more than specified, replace fuel filter/pressure regulator. If fuel pressure is as specified, go to step 11 .
9. Release fuel pressure. Raise and support vehicle. Disconnect fuel pressure line from fuel filter/pressure regulator at fuel tank. Connect Fuel Line Pressure Test Adapter Hose (6539) between disconnected fuel line and fuel filter/pressure regulator. Connect fuel pressure gauge to fuel line adapter hose. Turn ignition on. Using scan tool, actuate ASD fuel system test and note fuel pressure. Fuel pressure should be 53-63 psi (365-434 kPa). If fuel pressure is as specified, stop ASD fuel system activation. Release fuel pressure, and repair or replace fuel supply line. If fuel pressure is not as specified, stop ASD fuel system activation and go to next step.
10. Release fuel pressure. Remove fuel pump module and inspect fuel inlet strainer. If fuel inlet strainer is plugged, replace fuel pump inlet strainer. If fuel inlet strainer is not plugged, replace fuel pump module.
11. Turn ignition off. Release fuel pressure. Disconnect fuel supply line from fuel rail. Install Fuel Line Pressure Test Adapter Hose (6539 for 5/16" fuel lines or 6631 for 3/8" fuel lines) between disconnected fuel line and fuel rail. Remove fuel fill cap. Insert other end of hose into a graduated container suitable for gasoline.
12. Using scan tool, actuate ASD fuel system test for 7 seconds. If fuel volume is .5 pt. (.25L) or more, fuel volume is okay. Stop fuel system activation. Test is complete. If fuel volume is less than .5 pt. (.25L), check for a kinked fuel line between fuel pump module and fuel rail. Repair fuel lines as necessary and retest. If fuel line is okay, replace fuel pump module.

IDLE SPEED

Manufacturer does not list procedure for checking idle speed. Idle speed is controlled by PCM. No adjustment is required. PCM controls Idle Air Control (IAC) motor for proper idle speed. See SYSTEM & COMPONENT TESTING - CARS - EXCEPT SEBRING COUPE & STRATUS COUPE article for diagnosis of incorrect IAC motor operation.

IGNITION TIMING

Ignition timing is controlled by PCM and is not adjustable.

SUMMARY

If no faults were found while performing basic diagnostic procedures, proceed to appropriate SELF-DIAGNOSTICS article. If no diagnostic trouble codes are found during self-diagnostics, proceed to appropriate TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO-START, etc.) or intermittent diagnostic procedures.
