Where is the crankshaft position sensor located in the old Cruze?
2 Answers
Chevrolet Cruze crankshaft sensor is located inside the connection between the transmission case and the engine, which requires opening the engine hood for inspection. The function of the crankshaft position sensor is to determine the position of the crankshaft, i.e., the rotation angle of the crankshaft. It usually works in conjunction with the camshaft position sensor to determine the basic ignition timing. Below is an introduction to the Cruze: 1. Engine: The standard engine of the Chevrolet Cruze is a 1.4-liter turbocharged 4-cylinder gasoline engine. It delivers 153 horsepower and 130 Nm of torque. It offers high fuel economy, achieving up to 14.1 km/l on the highway. The biggest difference between the Cruze and its competitors is the optional diesel engine offered by Chevrolet. 2. Transmission: Whether equipped with a gasoline or diesel engine, the Cruze no longer offers a manual transmission. Therefore, the standard Cruze comes with a 6-speed automatic, while the diesel Cruze uses a 9-speed automatic. All models are front-wheel drive. To save fuel, all Cruze models are equipped with an engine idle start/stop system.
I used to own an old Cruze and replaced the crankshaft position sensor. It's installed at the lower front part of the engine, roughly where the oil pan meets the transmission. To be specific, you'll need to get under the car for a close look—it's usually secured with one or two screws on the engine bracket and sometimes hidden by other components. This sensor is absolutely critical because the car relies on it to monitor the crankshaft's rotation position for ignition. If it fails, the car either won't start or shakes violently. Once, mine malfunctioned on the highway, causing the car to stall abruptly—I had to pull over immediately. My advice: check it regularly; don’t wait for issues. If DIY-ing, just prepare a wrench, but be cautious with older cars as parts are brittle—avoid damaging the wiring harness. Snap a photo of its location for future reference. Since it’s tucked away, browsing forum tips saves time and effort.
