Having problems with your Cars & Trucks ?

Is the map sensor the same thing as the knock sensor on a 1999 daewoo nubira and exactly where is it located

Answers :

Not the same-the map sensor tells the computer how much air is in the intake to compute fuel requirements-map means manifold absolute pressure-look for it on the firewall or attached to engine-small black box with vacuum hoses, or at least one vacuum hose to it coming from the intake plenum.
The knock sensor is located on the engine block somewhere, maybe under the intake, it is for detecting engine "pinging"-or engine knock, the timing will be retarded a scheduled amount if any cylinders exhibit knock.
