SOURCE: Location of Oil Pressure Sensor and Oil Pressure Relieve Valve

the oil pressure switch is on pssenger side, lower engine area,beside oil filter, mounted in engine block. The pressure relief valve is in the oil pump, in which case, you have to drop the oil pan,and take off the oil pump.

SOURCE: o2 sensors on a 99 mercury cougar v6

I just got done replacing the O2 sensors in my 99 Cougar due to throwing a P0135 malfunction code. There's 3. Facing the engine there's one in the front coming off of the front header, which is easy to get to. Another more tricky one if between the engine and the fire wall on the rear header pipe. The third is under the vehicle behind the transmission pan on top of the exhaust. In order to replace the O2 sensor near the fire wall you will need to remove the 4 retaining bolts for the ECM module and move it out of the way. Additionally you will need to remove the 2 retaining nuts for a wiring harness that is seated below the ECM module. Pay close attention to the connectors because the front and under vehicle O2 sensors have round connectors the one near the firewall has a squared connector. I was able to replace all 3 by myself in approximately 35 minutes. If your throwing a O2 heater malfunction code it is most likely going to be the sensor near the firewall. make sure that you know someone with a code reader so the code can be cleared. If you're do for an emmissions inspection be sure to put at least 40 miles on the new O2 sensor with different types of driving (e.g. highway, coasting, decellerated turns and rapid acceleration). Gotta love project cars for your kids!!

SOURCE: where is the oxygen sensor

There will be 4 sensors in this system. One in each exhaust manifold on each side of the engine. Locate the catalytic converter under the car and you will see one just before the "cat" nearest the engine and one just after the "cat". What does the code say that was retrieved. This will help you identify which sensor needs to be replaced. Bank one sensor one is the side with the number one cylinder. Bank one sensor 2 is the one just before the "cat". Bank 2 sensor 1 is in the exhaust manifold on the opposite side of number 1. Bank 2 sensor 2 is after the "cat". I hope this helps. The size needed to replace the sensor is either 7/8" or 22mm. Either one will work. Soak liberally with a good rust penetrant at least an hour before.

Cougar fuel pump relay


there is a 30A fuse in the power line to the pump. Check for continuity, if the fuse is good check to see if there is 12v on the
relay input (black/yellow wire). If voltage is correct check the Mass air flow sensor operation ( you can find the procedure at the AutoZone web site in the repair manual section for your car). The MAF sensor sends the control voltage to the fuel pump relay, if that is good then the relay might be bad. If the CCRM was bad I believe it would produce a fault code. I hope this helps,

1989 Cougar, XR7, Supercharged-- I have zero fuel pressure. Is it most likely a relay, a fuse, or the fuel pump?


This sounds like the Inertia switch is tripped. This switch is either in the trunk or behind one of the kick panels. This is a resettable switch that cuts power to the fuelpump in a collision. Often a bump of the correct frequency will trip this.

You also have a fuelpump relay in one of the Powerboxes. The sequence is such that power goes to the relay and the wire from the relay goes rearward to the inertia sensor in the trunk(Or kickpanels) which acts like a breaker and then the power goes to the pump.

Were is crankshaft position sensor located on a 95 mercury cougar xr7?


First, if you would like to receive USEFUL information about your vehicle, (ESPECIALLY when you are asking about engine controls) it would be nice if you would mention WHICH ENGINE your vehicle is equipped with!

1995 Mercury Cougar XR7 was equipped with 3 different engines:
3.8L NON-SC VIN CODE [4]
3.8L SC VIN CODE [R]
4.6L V-8 VIN CODE [W]

The crank sensor for both of the 3.8L engines is located at the lower right FRONT of the engine.

The crank sensor for the 4.6L engine is located at the lower right REAR of the engine.
