What causes white smoke and misfire codes on Ford Escape vehicles?
Ford has issued a service bulletin #17-0028 to address a problem with Ford Escape (model years listed below) where the driver notices white exhaust and retrieves any of the following trouble codes:
P0217 P0217 Engine Overtemp Condition
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0304 Cylinder 4 Misfire Detected P0316
P1299 Cylinder Head Temperature Sensor Detected Engine Overheating Condition
The bulletin applies to 2014-2017 Ford Fusion and 2017 Ford Escape models with the 1.5L GTDI turbocharged engine. Ford has determined that the white exhaust condition is most likely caused by an intake manifold bolt that has backed out and damaged the charge air cooler.
The charge air cooler removes heat from the compressed air after it has left the turbo but before it enters the throttle body. Ford runs engine coolant through the charge air cooler and if the cooler is damaged, the airflow can pull coolant into the engine where it’s burned, causing the white smoke.
The fix involves replacing the intake manifold, bolts, and the charge air cooler. The bulletin applies to vehicles with above 10K
miles. The repair should be covered by the powertrain warranty but Ford has NOT extended the warranty beyond the original terms. It you’re past the powertrain warranty, you’ll have to pay for the parts and labor yourself.
Diagnose the cause of white exhaust
Ford recommends starting your diagnosis by performing a cooling system pressure test. Attach the pressure gauge and pressurize the cooling system. If the cooling system holds pressure for 5-mins, this bulleting doesn’t apply. If pressure drops, continue your diagnosis.
Check for coolant on the intake manifold
Disconnect the throttle body inlet pipe and set aside. Then disconnect the charge air temperature sensor. Loosen the pipe clamps and remove the throttle body rubber connector. Check inside the intake manifold. Ford says that the presence of engine oil in the bottom of the intake manifold is NORMAL. Don’t confuse the presence of oil with coolant. However, if you notice coolant, then you must replace the intake manifold and charge air cooler.
