Where is the location on a 2004 grand cherokee laredo 4.0 engine the temperature sensor.

The 2005 Jeep Grand Cherokee Laredo 3.7L typically has two oxygen (O2) sensors. One is located upstream (before the catalytic converter), often referred to as the pre-cat or upstream sensor, and the other is located downstream (after the catalytic converter), known as the post-cat or downstream sensor. In many cases, the upstream and downstream sensors are not the same and serve different purposes in monitoring and optimizing the air-fuel mixture and emissions.

hi , do you think if I replace crank sensor will solve the problem ,my jeep .... Where's the crankshaft located in 99 jeep grand Cherokee laredo .

no symptoms posted, just and wide range easter egg hunt and no engine or transmission options stated "drive line" which.?

there are many temp sensors. on jeeps. and more each year it seems.

1. EFI ENGine temperatures. ECT.
2. transmission temperature (TCM input)
3. outdoor air temp. (and option mine has... case in point)
4. air temperature of the air inducted in to the engine (EFI IAT)
5. HVAC , climate control temp sensors. at least 2.

post symptoms, then ask how to diagnose car.

This is what I found. Sorry no picture, no fig. 11

Fig. The coolant temperature sensor is installed in the thermostat housing (click image for zoom).

1. Partially drain cooling system until coolant level is below cylinder head.
   
2. Disconnect coolant temperature sensor wire connector.
   
3. Remove sensor from thermostat housing.

Hope helps (remember to rate ths answer).

The air temperature is taken between the air filter and the throttle body. Look in the roof of your air cleaner box. (usually 2-pin plug) After the air cleaner, the tube that sends the air to the throttle body has the mass air flow sensor in it.(usually 4-pin plug)

it is located under the battery in the battery tray.

I'm sorry I don't have more for you. I could not locate a dtc for "P1055", but did find some info for "P1035". It is for the bank 1, sensor 1 O2 sensor heater circuit. I would check fuse nos. 16 and 34 in the underhood power dist. center first. Next I would look at the connections to the O2 sensors, you should have 4 total. The catalytic convertors, yes there are two, are connected directly to the exhaust manifold, which is a split manifold. Cylinder nos. 1-3 empty into the front section while cylinders 4-6 empty into the rear section. There should be an O2 sensor before each convertor and after each convertor.

sometimes the air temp sensor is in the mass air too.
