The P3495 fault code indicates a problem with the exhaust valve control circuit in cylinder 12 of an engine. This code is typically stored in the vehicle’s onboard diagnostic system when the control circuit for the exhaust valve in cylinder 12 is registering a low voltage or resistance reading. This blog post will go over the symptoms, causes, and solutions for this fault code.
It is important to address this code promptly, as it can lead to decreased engine performance, increased emissions, and potential damage to the engine if left unresolved. Let’s dive into the details of P3495 and find out what it means for your vehicle.
What are the symptoms of code P3495?
When the fault code P3495 is present, you may experience one or more of the following symptoms:
- Check Engine Light (CEL) is illuminated
- Decreased engine power or performance
- Excessive exhaust smoke
- Difficulty starting the engine
If you notice any of these symptoms, it is recommended to have your vehicle inspected by a qualified mechanic to diagnose and resolve the issue.
What are the reasons for the P3495 code?
There can be several possible reasons for the P3495 fault code to appear. Some common causes include:
- Faulty exhaust valve control solenoid
- Wiring or connector issues in the exhaust valve control circuit
- Defective PCM (Powertrain Control Module)
- Cylinder 12 exhaust valve control circuit short to ground or open
These are just a few examples, and a proper diagnosis is necessary to pinpoint the exact cause of the issue.
What is the solution for code P3495?
In order to rectify the P3495 code, the following steps may be taken:
- Inspect and repair the wiring and connectors in the exhaust valve control circuit
- Replace the faulty exhaust valve control solenoid
- Check for short circuits or open circuits in the cylinder 12 exhaust valve control circuit
- If necessary, replace the PCM
It is essential to have the repairs performed by a qualified technician who can accurately diagnose and address the underlying cause of the fault code.
Summary
In summary, the P3495 fault code in cylinder 12 indicates a low voltage or resistance reading in the exhaust valve control circuit. This can lead to reduced engine performance, increased emissions, and potential engine damage if not resolved promptly. Symptoms may include a illuminated check engine light, decreased power, excessive exhaust smoke, and difficulty starting the engine.
The causes of this fault code can vary, ranging from faulty solenoids and wiring issues to defects in the PCM. A thorough diagnostic evaluation is necessary to determine the exact cause.
To resolve the P3495 code, it is recommended to have a qualified mechanic inspect and repair the exhaust valve control circuit, replace any faulty components, and address any short or open circuits. With proper repairs and maintenance, your vehicle will be back to its optimal performance.
