I need a diagram of the exhaust system on a 2000 ford taurus, 3L. 24 valve ohc.

The code is for the idle air control valve which controls idle speed.
The problem could be a faulty control valve, or a vac leak which is letting in air to the intake and bypassing the control valve.

Some models have two sensors, one before the catalyst and one after. This is done for a catalyst efficiency monitor that is a part of the OBD-II engine controls. The one before the catalyst measures the exhaust emissions right out of the engine, and sends the signal to the PCM about the state of the mixture as previously talked about. The second sensor reports the difference in the emissions after the exhaust gases have gone through the catalyst. This sensor reports to the PCM the amount of emissions reduction the catalyst is performing.

Hope helps.

How do I remove the front pulley assembly from the crankshaft extension on the front of a 24 valve OHC Ford Taurus engine.\r\nThe pulley has an integral bearing and nut assembly along with the mounting bracket which I have loose. It will not clear the extension shaft on the front of the crankshaft. The face of the pulley is against the fender wall.

The thermostat is located on the drivers side of the motor underneath a large wiring harness and is difficult to see. try following the top radiator hose backwards. Hope this helps....not too hard to change either.
DEPENDS. If it is the 24 valve OHC engine, the thermostat is on the passenger side, front, bottom of the engine. It's a little hard to get to but just two bolts.

which engine?

3L 2 valve

Not sure if you have the 3.0L 2V or the 3L 4V so heres both. Hope it helps.. Cobra,, :-)

check the inlet manifold gasket, just had mine changed on my Volvo 3L. It was cheap and we had exactly the same problem.

clogged cat converters.

Sell It

is it a 24 valve?
