Prolonged operation with this issue can further degrade engine torque.<\/p>\n<h3>Circuit Description<\/h3>\n<p>The ECM supplies 5 volts to the camshaft speed\/position sensor via the sensor power circuit and provides a ground through the sensor feedback circuit. The sensor generates a signal as the camshaft speed indicator passes, allowing the ECM to calculate engine speed and position.<\/p>\n<p>This sensor also serves as a backup if the primary crankshaft speed\/position sensor signal fails.<\/p>\n<h3>Component Location<\/h3>\n<p>The camshaft position sensor is located inside the transmission cover.<\/p>\n<h3>Diagnostic Conditions<\/h3>\n<ul>\n<li><strong>Runs Continuously:<\/strong> The diagnostic runs continuously while the engine operates.<\/li>\n<li><strong>DTC Activation:<\/strong> The ECM detects a sensor failure during engine operation and activates a white maintenance light or flashes the amber check engine light.<\/li>\n<\/ul>\n<h3>Actions if Trouble Code is Active<\/h3>\n<ul>\n<li><strong>Service Indicators:<\/strong> The ECM will turn on the white maintenance light or flash the amber check engine light.<\/li>\n<li><strong>Performance Impact:<\/strong> Extended operation with this fault results in reduced engine torque.<\/li>\n<\/ul>\n<h3>Clearing the Diagnostic Trouble Code (DTC)<\/h3>\n<ol>\n<li><strong>Repair Verification:<\/strong>\n<ul>\n<li>Perform a key cycle.<\/li>\n<li>Start the engine and let it idle for one minute.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Status Check:<\/strong>\n<ul>\n<li>Use the recommended electronic service tool to verify that the fault is inactive.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Light Reset:<\/strong>\n<ul>\n<li>The ECM will automatically turn off the maintenance or check engine light after successful diagnostics.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Command Reset:<\/strong>\n<ul>\n<li>Use the \u201cReset All Faults\u201d command in the service tool to clear active and inactive faults.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<h3>Shop Talk<\/h3>\n<p>Each ECM has a unique source address displayed when connected to a service tool.
