Description Icon Long Description

Fault code P0076 is logged when the engine control unit (ECU) has detected an issue with the intake valve control solenoid circuit in bank 1. This occurs when the voltage signal from the circuit is lower than the allowable limit.

The intake valve control solenoid is responsible for allowing air passage into the combustion chamber where it mixes with fuel.

A malfunction with the solenoid circuit can cause improper timing between the camshaft and the crankshaft. This can cause a host of issues with how the engine performs.

This falls under the variable valve timing (VVT) system that is found in modern cars. These systems are used to increase performance and efficiency when running the engine at various speeds.

Engines with VVT are most susceptible to this fault code. Hyundai and Kia are some of the most common manufacturers to have this fault code logged.

Warnings Icon Other Signs of This Problem

There can be various signs that indicate there is an issue with the air intake system. These will typically relate to how the engine runs and can be quite significant.

One of the most obvious signs is the presence of the Check Engine light on the dashboard – then this P0076 fault code appearing on an OBD2 reader.

Another fairly obvious sign will be that the vehicle may enter limp or failsafe mode.

Vehicle performance can also be greatly diminished. These can include things like worse fuel economy and noticeably decreased power. This is a given for a vehicle that enters limp mode.

Be sure to look out for other intake valve fault codes like P0075 and P0077. There can also be the same fault codes in bank 2 of the engine. These start at P0081.

Broken Down Icon What Could Be The Problem?

There are various potential causes for this issue. Most of these are found within the VVT system. However, because these are issues with the solenoid, they are most likely electrical in nature.

A faulty VVT solenoid itself is one of the most common causes. Additionally, this code can be caused by other circuit issues like faulty wiring or loose connections.

VVT systems rely on sufficient oil levels to operate properly. This means low engine oil can cause this issue.

In rare cases, the fault may lie with the ECU or powertrain control module. This can be from faulty software.

Fixed Icon Fixes

The fixes for this issue are specific to where the fault lies in the system. However, most of these are electrical in nature.

The first thing to check is the circuitry. Loose, damaged, or faulty wiring needs to be fixed. Loose connections must be fixed.

Additionally, checking the engine oil is a good idea. If the engine oil is low or dirty, it needs to be replaced.

If there are no faults here, a faulty solenoid is the next step. This needs to be replaced.

If all other parts are fine, the PCM software may need to be updated or the PCM itself may need to be replaced.

Danger Icon Seriousness

Fault code P0076 should be considered a moderately serious issue. The vehicle will be running to a lower standard than desired. It can also cause damage to the engine over prolonged operation.

It is a good idea to have this problem fixed as soon as possible.
