    DTC P0219: CRANKSHAFT POSITION SENSOR OVERSPEED SIGNAL

    1. Turn ignition on with engine off. Using scan tool, read engine RPM. If engine RPM is zero RPM with engine off, go to next step. If engine RPM is more than zero RPM with engine off, replace ECM. ECM is located on driver's side of engine, just in front of fuel transfer pump and contains a 50-pin connector. Perform TEST VER-2A .

    2. Turn ignition off. Remove air intake hoses from turbocharger and check turbocharger for signs of leaking oil seals. If no sign of leaking oil seals exist, go to next step. If signs of leaking oil seals exist, replace turbocharger. Perform TEST VER-2A . If signs of leaking oil seals exist, the charge air cooler and air intake system should be cleaned to prevent engine overspeed.

    3. Ensure ignition is off. Disconnect CKP sensor connector. CKP sensor is located on driver's side of cylinder block, just behind the starter. Fig. 35 . Inspect CKP sensor for damage electrical terminals. If CKP sensor electrical terminals are okay, go to next step. If CKP sensor electrical terminals are damaged, replace CKP sensor. Perform TEST VER-2A .

    4. Ensure ignition is off. Using scan tool in lab scope mode, connect lab scope lead to terminal "C" (Gray wire) on CKP sensor connector. Start engine and allow engine to idle. Check CKP sensor pattern in 10 millisecond range. If CKP sensor pattern is irregular, go to next step. If CKP sensor pattern is okay, shut engine off. Disconnect lab scope leads and reinstall CKP sensor connector. Check for use of alternate fuel such as starting fluid or propane, overspeed condition while going down hill, incorrect engine RPM reading, damaged ECM terminals, defective CKP sensor or tone wheel for CKP sensor. ECM is located on driver's side of engine, just in front of fuel transfer pump and contains a 50-pin connector. Tone wheel for CKP sensor is bolted to the crankshaft and aligns with opening for CKP sensor on cylinder block. Repair or replace components as necessary. Perform TEST VER-2A .

    5. Shut engine off. Ensure ignition is off. Disconnect negative battery cables. Remove starter for access to CKP sensor. Remove retaining bolt and CKP sensor. Inspect tone wheel for CKP sensor for damage. Tone wheel for CKP sensor is bolted to the crankshaft and aligns with opening for CKP sensor on cylinder block. If tone wheel is okay, replace CKP sensor. Perform TEST VER-2A . If tone wheel is defective, replace tone wheel. Perform TEST VER-2A .
