According to a recent report from GM TechLink, some units of the 2011- through 2016-model-year Chevy Cruze equipped with the turbocharged 1.4L I4 LUV gasoline engine may experience a loss of power or illuminated Check Engine Malfunction Indicator Lamp (MIL) in extremely cold conditions. After driving the vehicle, the performance issues may diminish. It’s possible that the following Diagnostic Trouble Codes (DTCs) may be triggered:
- P0299 (Engine Underboost)
- P0234 (Engine Overboost)
- P0236 (Turbocharger Boost Sensor Performance), P2227 (Barometric Pressure (BARO) Sensor Performance)
- P2261 (Turbocharger Bypass Valve Stuck)
- P00C7 (Intake Air Pressure Measurement System – Multiple Sensors Not Plausible)
It’s also possible that an increase in crankcase pressure may result in an oil leak around seals and gaskets.
For vehicles where a performance or drivability issue is present, GM recommends checking for ice blockage around the crankcase vent tube, ice accumulation on the intake manifold blocking the PCV passage in the cylinder head, ice accumulation in the charge air cooler restricting flow to the throttle body, and possible contamination at the charge air bypass valve (water, oil, or sludge).
GM recommends that a technician disassemble and clean the charge air bypass valve if contamination is discovered. Additionally, it’s recommended that the intake manifold be replaced, plus the charge air bypass valve, if needed.
If the Chevy Cruze’s turbocharged 1.4L engine is not producing the correct boost level, and there is no issue found with the turbo wastegate actuator or the turbo itself, it’s not recommended that the turbocharger is replaced. Rather, the charge air bypass valve should be cleared of any water or oil accumulation on the vacuum side port, and the intake manifold be replaced.
It’s also recommended that if any sludge, water or ice is found from the cylinder head, cam cover, or PCV pipes, including ice build-up blocking the cylinder head, the intake manifold should replaced.
Notably, the redesigned intake manifold includes a new intake positive pressure port location.
