It is not necessary to change those gaskets if all you have done is change the knock sensor. If they seem to be worn then you probably should go ahead and install new ones.
Manifold Absolute pressure measures the change in manifold pressures. It is an input or data gathering sensor that the computer uses for management.
It screwed in to the exhaust manifold. To change it you unplug the sensor and unscrew it with an O2 sensor socket.
The knock sensor on that vehicle is located under the intake manifold. The intake manifold must be removed to gain access to the knock sensor.
if the engine is a 2,4 liter, and if your replaceing the manifold gaskets, the manifold has 8 13mm bolts you need to remove, and also you need to drop the pipe, remove the 3 13mm bolts that connect to the rear pipe, then remove the four 15mm bolts that connect to the manifold, then you can remove the exhaust manifold, dont forget to remove the heat shield on top on the exhaust manifold 3 10mm bolts and one more item unplug the 02 sensor, you should be able to pull the manifold up and out of the way if your replaceing the gaskets, i just pulled the manifold off and up and bungy'd it up out of the way to clean the ports.
It is in the exhaust manifold next to the firewall.
By "exhaust manifold sensor" do you mean the O2 or oxygen sensor? The only sensor I know of on a exaust manifold is the O2 sensor and if you follow the manifold you will see 2 sensors sticking out they will have (usually) green wires coming from them
change your throttle positioning sensor located on the intake manifold
The knock sensor is under the intake manifold, which has to be removed. This should be left to an experienced mechanic.
air leak in the throttle or intake manifold gaskets or bad TPS sensor, disconnect TPS as a temporary fix
you mean ticking, right? Had the same problem with my 97 with the 3.9. It was an exhaust leak between exhaust manifold & head. New gaskets fixed the problem.
they are located under intake manifold The #1 sensor is located in the front of the engine and the #2 sensor is located in the back of the engine. Remember to replace the intake gaskets once you replace the sensor/s. The total time it took me to pull the intake and locate the bad sensor was about 6 hours. Hope this helps
It is under the intake manifold. Darn hard to get to and expensive to change.
