These DTCs may be caused by a binding or sticking intake camshaft sliding lobe pack. (Fig. 10) This condition is most likely to occur on vehicles with less than 10,000 miles (16,000 km).<\/p>\n<p style=\"font-weight: 400; text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-17089\" src=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2022\/12\/F10-camshaft-2A.png\" alt=\"\" width=\"740\" height=\"480\" srcset=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2022\/12\/F10-camshaft-2A.png 740w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2022\/12\/F10-camshaft-2A-300x195.png 300w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2022\/12\/F10-camshaft-2A-85x55.png 85w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2022\/12\/F10-camshaft-2A-200x130.png 200w\" sizes=\"auto, (max-width: 740px) 100vw, 740px\" \/><strong>Fig. 10<\/strong><\/p>\n<p style=\"font-weight: 400;\">If DTCs P30C3 (Intake Camshaft Profile Sleeve Position Sensor 2 Performance) and\/or P30BF (Intake Camshaft Profile Sleeve Position Sensor Performance), P30C7 (Exhaust Camshaft Profile Sleeve Position Sensor Performance) and P30CB (Exhaust Camshaft Profile Sleeve Position Sensor 2 Performance) are set, follow the diagnostics in the appropriate Service Information.
