P0462 is Fuel Level Sensor Circuit Low Voltage.Possible causes - Faulty fuel level sensor- Fuel level sensor harness is open or shorted- Fuel level sensor circuit poor electrical connection Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persist it may be necessary to replaced the fuel level sensor.

Yes there is a governor which limits the rpm to 2500 rpm. It ha been limited because beyond this rev, the engine gets overheated and if kept running it that condition would slowly but surely damage the engine badly. Once you have reached the limit naturally your cruise control will stop working since its supposed to maintain that speed, which is not allowed by the governor. This governor can be removed but then you will have to risk damaging your engine fatally........................sodeep

All you gotta do is hit the on button on your steering wheel then accelerate to any speed above 35 mph. Once there you press set and the cruise control takes over.

You need to bleed the Cooling system(While engine is on...) through the bleeder valve on top of the engine (w/ heater selected ON,and on High Speed ofcourse!).

• On the lower front passenger side of the engine there is an adjustable idler pulley for the AC. Loosen that center bolt a few turns to release the tension on the AC belt.
• Remove the old belt.
• Place new belt on.
• Tighten the idler pulley bolt until the belt is snug.
• Job complete.
• Hope this helps and thank you for using FixYa.

Here's a link on how to replace fuel pump.Here's the fuel filter repair guide.

Check for blowin fuses,

Check fluid level in the transmission if it is an Automatic or the clutch may need replacing due to wear if it is a manual gearbox.

Take off the pass side wheel and black wheel well cover....You will see it there...May have to pop off the air filter housing from the top to get to the terminals...with the right tools it took me about 40 minutes to change mine out.

It is just behind the headlight on the driver side. However I belive 2002 was the first year that the transmission computer and the engine computer where just one computer.

if it is the head gasket there will be coolant in the oil or oil in the coolant, I would check to make sure the electric fan is operating, could also be a stuck thermostat or clogged radiator (both of which are MUCH cheaper to check and repair than a head gasket change.
