Laymans terms

This code means that there's a problem with the part of the car that helps reduce pollution. It's like a special system that helps clean the car's exhaust, but something isn't working right.

Explanation

The P2062 code indicates an issue with the electrical circuit that controls the supply of reductant, which is used in the exhaust system to reduce emissions.

Technical description

The P2062 code is triggered when the Engine Control Module (ECM) detects an open or malfunction in the reductant supply control circuit. This circuit is responsible for controlling the delivery of a reductant, such as Diesel Exhaust Fluid (DEF), which is used to reduce nitrogen oxide emissions in diesel engines.

Symptoms

• Check Engine Light is on

• Poor engine performance

• Increased emissions

Common Causes

• Faulty reductant pump

• Open or short in the reductant supply control circuit

• Defective reductant control module

Glossary

Reductant: A substance used to reduce emissions, often Diesel Exhaust Fluid (DEF) in diesel engines.

ECM: Engine Control Module, the computer that controls engine functions.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the reductant supply control circuit wiring for damage.

• Test the reductant pump and control module for functionality.

Repair procedures

• Repair or replace damaged wiring in the reductant supply circuit.

• Replace the faulty reductant pump.

• Replace the defective reductant control module.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$200 - $600

Difficulty level

Moderate

Commonly affected vehicles

• Ford F-Series

• Chevrolet Silverado

• Ram 1500

Preventive measures

• Regular maintenance of the exhaust system

• Use high-quality diesel exhaust fluid

• Inspect wiring and connectors regularly

Error code type

Sensor Issue

User experience recommendations

• Have the vehicle inspected by a professional if the Check Engine Light comes on.

• Avoid ignoring the issue as it can lead to increased emissions.

• Ensure the use of the correct type of reductant fluid.

Warranty information

Check with the vehicle manufacturer for warranty coverage on emissions-related components.

Historical data

This code has become more common with the increased use of DEF systems in diesel vehicles to meet emissions standards.

Urgency level

Moderate – It should be addressed soon to avoid increased emissions and potential engine performance issues.

Testing conditions

• Engine running

• Vehicle in closed-loop operation

Component location

The reductant supply control circuit components are typically located near the exhaust system or under the vehicle.

FAQs

Q: What does the reductant system do?
A: The reductant system helps reduce harmful emissions from the vehicle's exhaust.

Q: Can I drive with a P2062 code?
A: It's possible to drive, but it is not recommended as it can lead to increased emissions and potential engine issues.
