\/><\/p>\n<ul data-start=\"920\" data-end=\"1145\">\n<li data-start=\"920\" data-end=\"994\">Use a multimeter to check the coolant temperature sensor&#8217;s resistance.<\/li>\n<li data-start=\"998\" data-end=\"1072\">At 80\u00b0C, the expected resistance should be approximately 323\u03a9.<\/li>\n<li data-start=\"1076\" data-end=\"1145\">If the resistance reading is incorrect, the sensor may be

the terminals in cavity 17 and cavity 3 are not loose or backed out.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<h2 data-start=\"1391\" data-end=\"1419\">Corrective Actions:<\/h2>\n<ol data-start=\"1420\"
