It's really pretty easy if you have the right tool. The sender requires a special socket. Buy a new sender from the auto parts store and rent or buy the socket from them. Disconnect the electrical connector from the old sensor. Then attach the socket to a ratchet and unscrew the old sending unit. Install the new one and reconnect the connector Remove oxygen sensor with special socket Ricks Free Auto Repair Advice
When you ask for help with your vehicle, I personally recommend that you mention WHICH 3.oL engine your vehicle is equipped with. I know that you probably did not know that there is two different ones. There is a 3.0L Dual Over-Head Cam (DOHC) engine (VIN Code "S"), and there is a 3.0L Over-Head Valve (OHV) engine (VIN Code "U"). Both of these engines are notorious for Mass Air Flow (MAF) sensors and vacuum leaks, however, these problems will cause problems on BOTH banks, not just one. You most likely have a "lazy" oxygen sensor. It just isn't switching like it should. The best way to diagnose this condition is to get the car on a scanner that can read sensor data and look to see what the downstream oxygen sensors are doing. If you have a lean code for the upstream sensor and you have high voltage readings (RICH or above 600 millivolts) on the downstream sensor, then the engine is not really running lean - the upstream sensor is lying and needs to be replaced.
Since you are getting a lean oxygen sensor code and it is using a lot of gas, I would say that this is most likely the case. An oxygen sensor that is lying to the computer about the system being lean will cause the computer to open the injectors wide open. Take a look at your tailpipe and see if it is really black. A normal exhaust pipe will look light tan in color. If the tail pipe is black, this is a really good indication that the system is actually running rich and the oxygen sensor is lying about it.
sensor 2 is normally the one after the cat but which side i wouldnt know for this model ,try testing them with a volt meter for the heater as this is what goes first ,the heater uses the two wires the same colour
Heated Oxygen Sensor (HO2S)
SPECIAL SERVICE TOOL(S) REQUIRED
Description
Tool Number
Oxygen Sensor Wrench
T94P-9472-A Removal and Installation
Disconnect battery ground cable (14301). Refer to Section 14-01 .
On 3.0L (4V) engine remove cowl extension and right side of leaf screen.
Disconnect engine control sensor wiring (12A581) from heated oxygen sensors (HO2S) (9F472). Do not remove harness connectors from the brackets.
Raise vehicle on hoist. Refer to Section 00-02 .
NOTE: If excessive force is needed to remove a heated oxygen sensor, lubricate the heated oxygen sensor with penetrating oil prior to removal.
Remove heated oxygen sensors from exhaust manifolds (9430) using Oxygen Sensor Wrench T94P-9472-A.
To install, reverse Removal procedure. Apply a coating of anti-sieze compound to threads of heated oxygen sensor. Tighten heated oxygen sensors to 34-46 Nm (26-34 lb-ft).
you have 2 ox sensors on that one before the cadalitic converter and one after it!!
first i would give it a complete tune up and change the fuel filter !!!!!!
In order to troubleshoot this, you must start with a clean engine wipe down.
The major offender parts are
air intake gasket on the manifold
air tube after the mass air flow sensor
rubber seal under idle air control IAC motor
===
Warm up the engine for 15-20 minutes (LEAVE THE engine at idle) then spray a little Barmen carburetor clear on the potential air leak location (ONE AT A TIME) and listen for a surge in rpm.
If the engine speed go higher that's mean the carburetor clean (ADDITIONAL FUEL) got into your engine and that's the gasket you need to change.
There may be multiple leaky spots so take your time and check all rubber gaskets,sensor and hose that are lead into the intake manifold.
When you finish fill up with one tank of Chervon to clean out the injectors.
Please post more information after your inspection.
Starter are one of the easier mechanical engine parts to change.
1) DISCONNECT THE BATTERY.
2) Disconnect the electrical cable running to the solenoid on the starter. 3) Remove the two bolts holding the starter in place.
4) Pull the starter out.
To install another starter, do the above steps in reverse order in reverse.
ok Bank 1 is the rear bank and bank 2 is the front bank sensor 1 in each bank is the one closest to the manifold they have green connectors sensor 2 is the sensor after the cat converter and is a blue connector
