Heated oxygen sensor (HO2S), crankshaft position (CKP) sensor and camshaft position (CMP) sensor [Skyactiv-x 2.0]
Caution:
– A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.
– Do not allow flammable objects such as the taping for bundling a wiring harness to come into contact with the exhaust manifold and silencer.
– If foreign matter such as metal shaving adheres to the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence, which can negatively affect the engine control. Verify that there is no foreign matter on the CKP sensor when replacing.
