P1258 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• increased fuel use
• reduced performance
• rough operation in certain conditions

Common causes

• Control module logic or calibration issue affecting pedal correlation pds1 and pds2
• Component failure in the monitored system
• Connector pin damage/corrosion or harness stress near related components

How to diagnose P1258

1. Confirm P1258 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to pedal correlation pds1 and pds2 for obvious defects.
3. Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P1258

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

Can you drive with P1258?

The vehicle is often drivable with P1258, 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)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (generic) in the pedal correlation pds1 and pds2 circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify P1258 remains cleared under the conditions that originally set the code.

Fix options

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

Typical repair cost

$100-$450

Common mistakes when diagnosing P1258

• 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.

P1258 in common vehicles

P1258 appears across makes such as Mazda, Subaru, Lexus, Jeep. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P1258?

P1258 is commonly set by generic faults affecting pedal correlation pds1 and pds2.

How much does it cost to fix P1258?

For P1258, repair costs are typically $100-$450 depending on exact root cause, labor rates, and part quality.

Can I clear P1258 without repair?

You can clear P1258 temporarily, but the code usually returns until the underlying fault is corrected.
