This is often due to improper timing between the crankshaft position (CKP) sensor and camshaft position (CMP) sensor.<\/p>\n<h3>Related Contents:<\/h3>\n<p><a href=\"https:\/\/www.obd2tool.com\/goods-10593-ISUZU-TRUCK-DIAGNOSTIC-KIT-with-ISUZU-IDSS-GIDSS-and-EIDSS-Softwae.html\">ISUZU IDSS MX2-T Diagnostic Tool<\/a><\/p>\n<h3>DTC P0016 \u2013 CKP vs. CMP Sensor Information<\/h3>\n<ul>\n<li>CKP Sensor Location: Mounted on the rear left side of the cylinder block, it reads a rotor attached to the crankshaft with 56 notches spaced 6\u00b0 apart and a 30\u00b0 opening indicating the top dead center (TDC) of cylinder #1.<\/li>\n<li>CMP Sensor Location: Installed on the timing sprocket cover at the front of the cylinder head, it detects five lobes per engine cycle from a sprocket with four bosses spaced 90\u00b0 apart and one reference boss.<\/li>\n<\/ul>\n<p>The ECM correlates the CKP and CMP signals to ensure proper engine timing.
