My 2008 Ford Explorer v8 is throwing code p0196, which once researched is the EOT sensor. Need to know where it is located on my vehicle.

its the EGR Vacuum Regulator or the egr itself it may just need removing and cleaning out with some cab cleaner. can get block from exhaust blacking.

the o2 sensor is located by the catalytic converter and anaylyses the exhaust emissions,it may need a tune up but first i'd check all air intake hoses for leaks ,signs of wear etc as if the air/fuel mixture going into engine isn't correct the emissions will not be either ,you can get fuel additives which will clean cylinder,valves and the cat converter so try this first , if the light is still on get the garage to clear the OBD memory and retest drive as a stored code isn't always automaticly erased

I would suspect a failed fuel injector,been an issue
for 5.4 V8 3 valve engines on some years,check your
year & the various issues


Do you have a MIL Lamp light on dash?

Check for codes like PO 201 thru 208

Check recalls & use internet to research issue

After you resolve the problem, install the champion
one piece spark plugs---# 7989

The front or upstream oxygen sensors get replaced
on all your vehicles at 100,000 miles,after you fix the
leaking injectors

P0296 Cylinder 12 Contribution/Range Fault
Is triggered when the Power Train Control Module (PCM) detects that the acceleration rate of the crankshaft for Cylinder #12 was less than a calibrated amount. During normal conditions the PCM turns the Fuel Injectors ON and OFF in the Fuel Injection System.
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine Misfire
- Engine Run Rough
- Low MPG

Possible Causes:
- Fuel Injector #12
- Faulty or Corroded Fuel Injector #12 Connector
- Plugged #12 Fuel Injector
- Dirty #12 Fuel Injector

Possible Solution:
- Clean Fuel Injector #12 Connector
- Clean Fuel Injector #12
- Replaced Fuel Injector

P0298 - Engine Oil Over Temperature Condition
Indicates the Engine Oil Temperature Protection (EOT) strategy in the Power Train Control Module (PCM) has been activated. This temporarily prohibits high engine speed operation by disabling injectors, reducing the risk of engine damage from high engine oil temperature. Note: On engines which are equipped with an oil temperature sensor, the PCM reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Surge

P0298 is set when the vehicle has been running below 1,000 rpm and less than 20 mg/stroke MFDES with EOT sensor signal reading above 110C (230F). The time to set the fault is dependent on EOT and Intake Air Temperature (IAT) temperatures, and can vary between approx. 15 to 45 minutes

Possible Causes:
- Very high engine RPM for an extended period of time.
- Overheating condition.
- Malfunction EOT sensor or circuit (vehicles w/EOT sensor).

Possible Solution:
1. Inspect EOT sensor circuitry at sensor and PCM. Inspect for damage, loose or pushed-out pins, loose or poorly crimped wires
2. If connectors are ok check cooling system, radiator, fan/clutch operation, thermostat
3. If cooling system is ok carry out KOEO On-Demand Self Test
4. If other fault codes are present after test repair them, if only P0298 is present clear codes
5. Let vehicles sit for 8 hours and then KOEO
6. Monitor EOT in live data
7. If EOT sensor reading is above 110*C(230*F) replace sensor
8. IF EOT is below 110*C check continuous memory DTCs
9. If P0298 is present replace PCM

Hope helps (remember rated and comment this).

P1405-Differential Pressure Feedback Electronic (DPFE) sensor upstream hose off or plugged - or cracked.

I believe it is on the driver's side of engine about half-way down. also, check all other hoses for damage
