P1004 Dodge Charger: A To Z Guide To Deal With

What does the P1004 Dodge Charger mean? The P1004 code for Dodge Chargers indicates that there may be a problem with the Short Runner Valve system.

Well, the Short Runner Valve or SRV system is usually used to improve the performance of the engine. It is mainly designed to open and close quickly, allowing the engine to operate at higher speeds. Also, the SRV can help to improve the emissions of an engine. This is because they can help to burn fuel more completely, resulting in fewer emissions.

So, we have arranged this article to find out the reasons, symptoms, and possible solutions to get rid of this code and keep the engine’s performance up to the mark. Have a look-

P1004 Dodge Charger Error: Reasons, Symptoms & Solution

The P1004 code mainly indicates that the Engine Control Module (ECM) has detected a problem with the intake manifold pressure sensor or circuit. This is related to the Short Runner Valve system, which plays a vital role in the overall performance of the car’s engines.

However, this system helps to pass air between the intake manifold interface and the manifold plenum through the bypass.

Again, the Powertrain Control Module (PCM) calibrated the open and close circuit range. So far, the P1004 code is set when the ECM detects an abnormal voltage reading from the intake manifold pressure sensor. This sensor is used to measure the pressure inside the intake manifold. The ECM uses this information to regulate the air/fuel mixture and engine timing. If the sensor is not functioning well, the ECM will not be able to properly adjust the engine settings.

This can lead to several problems such as poor fuel economy, increased emissions, and engine performance issues.

Let’s have a look at the P1004 Dodge Charger symptoms along with the possible reasons in the below table.

You may face the symptoms above for the P1004 Dodge Charger from 2006 to 2013. In this circumstance, now we are depicting the possible solution for each reason. Here we go-

Poor Electrical Connection

A Solution for the poor electrical connection of an engine is to check the engine’s ground strap. The ground strap is a heavy wire that connects the engine block to the frame of the vehicle. Over time, the ground strap can become corroded or broken, which can cause electrical problems.

If the ground strap is corroded, it can be cleaned with a wire brush. If the ground strap is broken, it will need to be replaced.

Another possible solution for the poor electrical connection of an engine is to check the battery cables. The battery cables can become corroded or damaged, which can cause electrical problems. If the battery cables are corroded, they can be cleaned with a wire brush. If the battery cables are damaged, they will need to be replaced.

SRV Harness Is Open Or Shorted

If you have a problem with the SRV, service engine soon light coming on, it can be due to an open or shorted circuit in the engine harness.

The SRV light is controlled by the powertrain control module or PCM and is used to indicate a problem with the engine. When the light is on, it means that the PCM has detected a problem and is trying to diagnose it.

If you have an open or shorted circuit in the engine harness, it can cause the SRV light to come on. So, the circuit may be open because of a break in the wire or a loose connection.

In that case, inspect the SRV harness for any signs of damage, such as fraying or exposed wires. If any such damage is noticed, repair or replace the harness as necessary.

Faulty Short Runner Valve Assembly

If your car’s engine is idling too high, it could be due to a faulty short runner valve assembly. The short runner valve, or SRV, is responsible for regulating the air intake into the engine. If it’s not running properly, it can cause the engine to idle too high. However, you will find a few possible solutions to this problem.

 First, you can try cleaning the SRV assembly. This can be done with a can of compressed air and a brush. Just don’t forget to wear gloves and have eye protection while you’re doing it. If cleaning the assembly doesn’t work, you may need to replace it.

Faulty Powertrain Control Module (PCM)

A faulty powertrain control module or PCM can cause your engine to run erratically. Your check engine light may also come on, and you may notice reduced fuel economy. In some cases, the PCM may cause the engine to stall.

There are several possible solutions for a faulty PCM. One is to have the module professionally rebuilt. This can be done by a company that specializes in remanufacturing PCMs. Another solution is to replace the PCM with a new or used unit.

Damaged Engine Sensors

Damaged engine sensors are a common problem with modern cars. There are a few possible solutions to this problem, depending on the severity of the damage. The first and most obvious solution is to replace the damaged sensor.

Besides, the best solution for damaged engine sensors is to prevent them from becoming damaged in the first place. This can be done by just regularly cleaning and maintaining your engine and by using quality parts.
