Hi, I'm guessing that you are getting better fuel pressure with a full tank. this might point to a faulty fuel pump or possibly a blocked fuel filter.

SOURCE: engine runs bad at half tank or less

Ok ready for this one,new gas cap,its true cars with bad gas caps will cause the check engine light go on,or your problem,it has to be pressurized when full and no air in the tank its ok,but as you use gas and have air in the tank with the low fuel the air pressure is leaking pass the cap,thus losing pressure,too bad you had to fix all the other stuff but look at it as an investment,after this works please give me a fix ya thanks

SOURCE: 2001 Hyundai Sante Fe Transmission Filter Location

The filter sits on top of the transmission. look under the hood on drivers side it screws right on top of the transmission. It looks like an engine oil filter.

My 1991 honda civic dx sedan jerks after getting below a half tank of gas


check the hose in the fuel tank, the hose going out of the tank may have holes causing the fuel to go out and back to the tank.

If it has a timing belt,that is your problem

The exhaust converter & all the oxygen

I have a 2002 Hyundai Sante Fe. The check engine light has been on for months.No one can seem to find out why. Every time I fill up the gas tank I have a problem restarting the engine - I have to play with...


My educated guess is that the purge control valve is stuck in the open position. This valve is part of the emissions system on your Santa Fe and normally is closed when the engine is turned off. If the valve sticks open, fuel vapor gets pushed into the engine when filling the fuel tank. This creates a fuel mixture that is too rich on the next start up.

I received a P1154 OBD code error. It says


DTC P0131 or P0151
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The powertrain control module (PCM) supplies the HO2S with a reference, or bias, voltage of about 450 mV. When the engine is first started, the PCM operates in Open Loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperature and Closed Loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream. Low HO2S voltage indicates a lean exhaust stream. If the PCM detects an HO2S voltage that stays below a specified value, DTC P0131 sets for HO2S bank 1 sensor 1, or DTC P0151 sets for HO2S bank 2 sensor 1.

How much does it cost to replace a fuel pump on 04 hyundai sante fe?


fuel pumps are kindda expensive, especially on import vehicles. Number one cause for fuel pump failures is heat. When your rinding with the fuel below half, the pump is party exposed inside the fuel tank and when exposed for periods of time it tends to heat up and then gradually burns out cause you to replace it. It's ok to go below half but not to often, I hope it helped abit.

1993 honda civic


Try checking the snorkel tube between the air cleaner and the intake. Open the hood, and have a friend try to rev the engine, and watch the tube...my '92's was collapsing and starving the engine, couldn't get more than 3500-4000 rpm. Could also be a fuel pump problem like low pressure or bad line.
