The vehicle must be driven until the Cleaning Exhaust Filter message is extinguished. That does not dismiss the fact that within the engine's elaborate system of sensors, modules, and electronics, that it does not play an integral role in engine operation. Still, there are some things that you can check. Space is tight in either instance, and you'll find that a long pick is useful in removing the sensor from the engine block once it is unbolted. Our scanner are showing fuel pressure desired and actually within good tolerance of each other until the truck goes into limp mode somewhere around 1800rpm and above. To achieve sufficient fuel vaporization, most port fuel injection systems work at moderate pressures, 35-75 psi.
Each occurrence will last from 10-40 minutes. To find the right fix, begin your diagnosis at the air intake. Liquid fuel is an obvious sign of a leak, but residue may or may not be an indicator. If you find your after-market chip is the cause of the problem, it might make sense to remove it permanently. Not sure what next to do.
The petcock is located on the bottom of the radiator on the driver side. For most driving conditions, normal exhaust filter regeneration will begin anywhere from 100-600 miles 161-966 km from the completion of the last regeneration cycle. In industry, for example, waterjets are used to cut through stainless steel and stone, so your finger would present no problems for the high pressure direct injection system on your car. Pressure testers are indeed available, but these require tapping into the fuel system, which may cause more problems than they solve. The amount of white smoke during this time will be increased during exhaust filter regeneration. Note: Testing fuel pressure might seem the obvious diagnostic step in this situation, but the problem is that most vehicles with direct injection systems do not have fuel pressure testing ports, not even on the low side.
If the oil level is higher than normal and smells like fuel, suspect a leaking fuel injector. Proper torque is critical, and may require a special tool to ensure proper sealing. The electrical resistance of the thermistor decreases as temperature increases. Please see the Customer Information Sheet for additional information. The crankshaft position sensor for a 6.
Refer to the repair manual for the proper procedure for your vehicle. Look for fuel residue or liquid fuel. Because the fuel is injected in the compression stroke when cylinder pressure is approaching maximum, the fuel injectors need to run at much higher pressures. More will be added as we go! The sensor modifies a voltage signal from the Engine Control Module. Drain the coolant into clean containers if you wish to reuse it. A dirty air filter can trigger this code, but so could a blockage further into the intake so be sure to trace airflow from the airbox all the way to the intake manifold.
High-pressure fuel systems rely on precisely machined surfaces and tight tolerances for leak-free operation. That being said, any diagnosis or repair usually starts with depressurizing the system. If the fuel injector is stuck open, perhaps due to contamination or damage, fuel will constantly leak from the injector, leading to an unexpected drop in fuel pressure. Adjust or repair as necessary. What are the symptoms of code P0093? You may experience hard starting or no starting. Installing a stainless steel fuel line, for example, you would not want to scratch the sealing surface or bend the line, as doing do would compromise the seating and sealing of the connection. The pressure and spray, in combination with high intake and cylinder temperatures, helps the fuel to vaporize even better, for better power output and fuel economy.

Caution: The high pressure fuel system can be dangerous to work on. What are the common causes of code P0093? The rear bolt is the most difficult to reach and patience is required to loosen it. Under the hood, if there is an external leak, you may see or smell a fuel leak. You can see the head of the bolt and use a finger to align a wrench on it by looking through a hole in the crossmember spanning from framerail to framerail beneath the engine.
It is located at the rear of the compressor between the compressor housing and engine block. Depending on the nature of the failure, you may notice various problems with your vehicle. Make sure connectors are fully engaged, no bent or backed-out pins or corrosion. P0198 Ford Description The engine oil temperature sensor is used to detect the engine oil temperature. Trouble Code Fault Location Probable Cause P0093 Fuel system leak -large leak detected Wiring, fuel pressure sensor, mechanical fault We recommend What Does Code P0093 Mean? Open the air box and look for blockages. . Do not forget to refill the radiator with engine coolant.
