P0295 Code: Meaning, Symptoms, Causes & Fix

Overview

Code P0295 indicates a fault in Cylinder 12 Injector Circuit High, typically within fuel delivery and pressure control.

Symptoms

engine may stall at idle
hard starting
reduced fuel economy

Common causes

Open circuit in wiring affecting cylinder 12 injector circuit high
Disconnected or loose connector
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0295

Confirm P0295 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to cylinder 12 injector circuit high for obvious defects.
Use a continuity test from module pin to component to identify opens/high resistance.
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 P0295

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with P0295?

Most vehicles can be driven short-term with P0295, but postpone heavy load/highway driving until repaired.

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 (open) in the cylinder 12 injector circuit high circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0295 remains cleared under the conditions that originally set the code.

Fix options

Restore continuity and verify pin tension.
Clear corrosion and protect terminals.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$220-$1100

Common mistakes when diagnosing P0295

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.

P0295 in common vehicles

P0295 appears across makes such as BMW, Mercedes-Benz, Audi, Volvo. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0295?

P0295 is commonly set by open faults affecting cylinder 12 injector circuit high.

How much does it cost to fix P0295?

For P0295, repair costs are typically $220-$1100 depending on exact root cause, labor rates, and part quality.

Can I clear P0295 without repair?

You can clear P0295 temporarily, but the code usually returns until the underlying fault is corrected.
