P0795 Code: Meaning, Symptoms, Causes & Fix

Overview

When P0795 appears, the control module has detected abnormal behavior related to Pressure Control Solenoid C in powertrain controls.

Symptoms

rough operation in certain conditions
check engine light
increased fuel use

Common causes

Control module logic or calibration issue affecting pressure control solenoid c
Electrical fault in the affected circuit
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0795

Confirm P0795 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to pressure control solenoid c for obvious defects.
Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0795

Low: This code is low to moderate severity in most cases, but diagnosis is still recommended to avoid recurring warnings.

Can you drive with P0795?

The vehicle is often drivable with P0795, but plan a repair window to prevent repeat faults.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (generic) in the pressure control solenoid c circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0795 remains cleared under the conditions that originally set the code.

Fix options

Inspect circuit and connector condition.
Clear code and confirm through drive cycle.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$100-$450

Common mistakes when diagnosing P0795

Replacing parts without verifying voltage, ground, and signal integrity first.
Ignoring related stored/pending codes that indicate upstream faults.
Skipping post-repair verification drive cycle and readiness checks.

P0795 in common vehicles

P0795 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0795?

P0795 is commonly set by generic faults affecting pressure control solenoid c.

How much does it cost to fix P0795?

For P0795, repair costs are typically $100-$450 depending on exact root cause, labor rates, and part quality.

Can I clear P0795 without repair?

You can clear P0795 temporarily, but the code usually returns until the underlying fault is corrected.
