Laymans terms

The car's computer is saying that something is wrong with the system that helps reduce pollution. It's like a special door that helps clean the air from the engine isn't working right.

Explanation

The P2141 code indicates a problem with the electrical circuit that controls the EGR (Exhaust Gas Recirculation) throttle. This system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine.

Technical description

The EGR throttle control circuit is responsible for regulating the position of the EGR valve. When the control circuit voltage is lower than expected, the engine control module (ECM) triggers the P2141 code. This could be due to a short circuit, poor connection, or a faulty EGR throttle control motor.

Symptoms

• Check Engine Light is on

• Reduced engine performance

• Increased emissions

Common Causes

• Faulty EGR throttle control motor

• Short circuit in the EGR throttle control circuit

• Poor electrical connection in the circuit

Glossary

EGR: Exhaust Gas Recirculation

ECM: Engine Control Module

Diagnosis steps

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

• Inspect the EGR throttle control circuit for damaged wires or poor connections.

• Test the EGR throttle control motor for proper operation.

Repair procedures

• Repair or replace damaged wiring or connectors in the EGR circuit.

• Replace the EGR throttle control motor if faulty.

• Clear the code and test drive to ensure the issue is resolved.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$150 - $400

Error code type

Sensor Issue

User experience recommendations

• Do not ignore the check engine light.

• Have the vehicle inspected by a professional if unsure.

• Regularly check and maintain the EGR system.

Warranty information

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

Historical data

The P2141 code has been associated with vehicles that have high mileage and inadequate maintenance of the EGR system.

Urgency level

Moderate – Addressing this issue will help maintain engine performance and reduce emissions.

Testing conditions

• Engine at operating temperature

• Vehicle at idle

Component location

The EGR throttle control motor is typically located near the intake manifold or the EGR valve on the engine.

FAQs

Q: Can I drive my car with a P2141 code?
A: It's possible to drive, but it's not recommended as it can lead to increased emissions and potential engine performance issues.

Q: How do I clear a P2141 code?
A: After repairing the issue, use an OBD-II scanner to clear the code from the vehicle's computer.
