question about sensor location.
hello
my check engine light was on so i used my code reader and got a code "133" which according to the book said was a "o2 sensor slow to respond" well according to my haynes manual it said that the code was refering to the "air charge temperature sensor in a "stuck open" state. well this would correspond with a broken check valve on my exhaust gas recirculation system. so i went and got a replacement check valve (god bless napa they had only one in WHOLE town) and a new a.c.t sensor. so i replaced the check valve and went to replace the sensor jic and looked in the haynes book at the picture.... well on my truck where the sensor is supposed to be is nothing .. no hole.. nothing capped off... its just not there... does anyone no where this sensor is?? do i really need to replace it?? i figure with the truck getting up on mileage and i had already bought it it would be a good idea to go ahead and replace it since i had already replaced the check valve.. but where is this sensor supposed to be???
