Engines need to choose between being fuel-efficient and powerful, they cannot be both at any given time. Variable valve timing allows modern engines to alternate between the two personas depending on driver inputs and the driving conditions. If there’s an issue with the variable valve timing camshaft position actuator control circuit, then the P2088 code or other related trouble codes can be stored.

What Does the P2088 Code Mean?

The P2088 diagnostic trouble code (DTC) is defined as “A” Camshaft Position Actuator Control Circuit Low Bank 1. The camshaft is responsible for opening and closing the intake and exhaust valves of each cylinder. Many vehicles have a dual overhead camshaft design with two camshafts. With such a setup, one camshaft is for the intake valves, and the other is for the exhaust valves.

Most modern vehicles have variable valve timing (VVT). In a typical VVT system, the PCM uses an actuator on the end of the camshaft to alter the camshaft’s position, thereby changing the valve timing. The PCM operates the actuator via an electronic oil control solenoid.

Code P2088 is set when the PCM detects a problem with the actuator oil control solenoid or its circuit on bank 1.

Note: The definition of code P2088 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P2088 Code?

• Failed variable valve timing actuator oil control solenoid
• PCM failure or software in need of an update
• Faulty wiring

What are the Common Symptoms of the P0348 Code?

• Illuminated check engine light
• Decreased engine performance
• Decreased fuel economy

How to Diagnose the P0348 Code

Diagnosing a P0348 code usually involves inspecting various engine components. The process can have various additional steps, depending on the vehicle’s year, make, and model. If you aren’t familiar with your vehicle and the required steps, it might be best to have a certified mechanic do the job for you.

How to Fix the P0348 Code

There isn’t a magic bullet fix for any DTC. Troubleshooting steps may vary depending on the vehicle manufacturer because the camshaft sensors and their wiring can have different designs and layouts. Under these circumstances, bringing your vehicle to a trained professional might be your best bet to resolve the issue.

Of course, you can do the job yourself if you have the necessary automotive knowledge. Before you work on your vehicle, however, make sure to have the right technical information. Luckily, this information is available online. Chilton guides or an ALLDATA subscription contain vehicle-specific repair information, so you might want to check those out before you begin.
