FAQs

What is code spn 3464? ›

SPN 3464/FMI 16 - GHG14. Description. Intake Manifold Pressure Over-boost Detected During a Regeneration. Monitored Parameter. Intake Manifold Pressure.

If the Throttle Actuator Control is completely unable to open and close the throttle plates, then the vehicle will not accelerate, which means that you won't be able to drive the car at all. It may also put the car into Home Limp Mode, which can make it very frustrating to drive.

This assembly is usually located between the air filter and the intake manifold. When you depress the gas pedal, the plate in your throttle body assembly should move at an angle to allow more air into your engine. More air in the engine equals more fuel and more power.

SPN is short for suspect parameter number. It identifies which electrical circuit, part or component of your truck isn't working properly.

SPN stands for Suspect Parameter Number. It's a diagnostic trouble code that provides detailed information about specific faults detected by the vehicle's ECU, making it easier to identify and address issues within the vehicle's electronic systems.

Has your car's throttle body stopped working properly? It's best to immediately replace the faulty engine part and refrain from driving your vehicle until you complete the repair.

The average cost for a Throttle Body Replacement is between $515 and $650. Labor costs are estimated between $87 and $109 while parts are priced between $428 and $541. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

Filth, carbon, and dirt can build up in the housing creating problems with air flow. Known as co*king, the normally smooth service for air to travel becomes full of gunk and creates an imbalance. This interrupts that perfect mixture of air and fuel which can cause the butterfly valve to get stuck.

Can you clean a throttle actuator? ›

Cleaning fuel injectors is generally not a do-it-yourself project, but you can clean the throttle body on your vehicle with common tools and specialized spray cleaners.

When the throttle body is not operating effectively, one of the tell-tale signs is poor or low idling. This includes the engine stalling after coming to a stop, a very low idle after starting, or stalling when the accelerator pedal is pressed down rapidly.

You have two options in this situation you can either replace the throttle body and perform a relearn calibration. Or you can disconnect the battery And reconnect it allowing the faults to clear.

Generally electronics inside Throttle Actuators fail around 55k miles, the gear wear inside this unit at that mileage would be present on just 3 teeth and you will see some fine dust inside. This is normal, sadly people believe this tiny wear cause intermittent failures.

Ignition Bypass Circuit Error

The ECM monitors the Ignition Bypass circuit and will set code 42 to signal an error. The ignition bypass circuit allows the ECM to switch the ignition module from "base" timing to computer-controlled timing advance.

Based on the number of poles, the breakers are classified as – SP –Single Pole, SPN – Single Pole and Neutral DP – Double pole, TP – Triple Pole, TPN – Triple Pole and Neutral, 4P – Four Pole.
