What causes an engine surge when the ECU is off?

If closed TPS voltage changes, the ECU may assume that your foot is on the throttle, causing a richer fuel mixture to be delivered. This can also be caused by a faulty TPS, or even a poor ground. With the engine off, check TPS voltage with the accelerator pedal relaxed. Then work the pedal a few times and see if the voltage changes.

What causes an engine surge during fuel injection?

In combination with the camshaft position sensor (CMP), the CKP signals are used by the ECU to manage fuel injection and spark delivery. A faulty CKP (or CKP circuit) can easily cause an intermittent misfire, which naturally results in what the driver may perceive as a surging effect.

What causes a car to start and then die?

But if there is a fuel leak somewhere, then the proper amount of fuel won’t be able to make it to the combustion chamber. This might cause the engine to still start, but it won’t be able to keep it running. That is why it will die almost immediately after it starts.

What are the symptoms of a car dying while driving?

You may experience different symptoms: On deceleration, engine rpms may fall below normal idle speed and stall. When reaching a stop light, the engine may jerk and die. While driving, the engine may suddenly shut off.

What causes a car engine to start surging?

Vacuum Leaks. Vacuum leaks can cause surging on some engines, but it depends on the type of fuel injection system. The MAF (mass air flow) systems used on many cars measure the amount of air flowing through the engine’s throttle valve (throttle body) and use that information to determine how much fuel to inject.

What causes a no start on a 6.0L diesel?

Rough start, no start, and rough running conditions often occur due to the FICM, or Fuel Injection Control Module. The FICM supplies 48 volts to the two solenoids that control oil flow to the fuel injector. Excessive heat from the engine and vibration can cause the FICM to overheat or fail.

What are the symptoms of a bad throttle position sensor?

This is another failure mode of the TPS, which indicates that it is falsely limiting the power being requested with your accelerator pedal foot. You may find that your car will accelerate, but not beyond a speed of 20 – 30 MPH. This symptom often goes hand in hand with loss-of-power behavior.

What causes the RPM to go up and down?

Hi there. For the engine surging making the rpm’s go up and down could be caused by a defective or stuck idle air control valve (IAC). Check the IAC and see if it’s working.

What causes a Ford Expedition to stall at a stop?

Bad Solenoid. When your Ford Expedition stalls at a stop, just as it would if it had a manual transmission and you neglected to push in the clutch, that’s a sign that one of the solenoids is malfunctioning or has gone out.

How is the transmission of a Ford Expedition controlled?

Electronic transmissions are controlled by a computer, otherwise known as the powertrain control module (PCM). Troubleshooting the PCM is a complex job that requires some special test equipment that the average do-it-yourselfer does not have—nor is cost effective for them to purchase.

What does overdrive cancel mode do on a Ford Expedition?

What does the PIP signal on a Ford Expedition mean?

The ignition control module generates a profile ignition pickup (PIP) signal (engine rpm) and sends it to the PCM. The PIP is one of the inputs that the PCM uses to determine transmission strategy, Wide-Open Throttle (WOT) shift control, torque converter clutch control, and EPC pressure.

Why is my Ford F150 stalling at idle?

EGR works properly. This problem is only in closed loop. While the engine is cold everything seems to work fine. I can open the throttle a bit, say 1500, and there’s a surge, or maybe you could call it an “anti-surge” where the rpms will drop a bit and engine roughens up a bit, then it goes back up and smooths out, then cycles back down.

Can a loose fuel filter cause a car to stumble?

In some cases, the connections on the fuel filter may be loose, causing fuel to leak from the fuel lines or the fuel filter. This can cause engine stumbling issues. If you notice this problem, replace the fuel filter with a new one and retighten the fittings.
