Laymans terms

This code means that the car's computer thinks there is too much air pressure in the engine compared to the outside air. It's like when you blow up a balloon too much and it might pop!

Explanation

The engine control module (ECM) has detected that the charge air pressure is too high when compared to the barometric pressure on Bank 2 of the engine.

Technical description

P1182 is triggered when the ECM detects that the charge air pressure sensor reading is significantly higher than the barometric pressure sensor reading. This can indicate a problem with the turbocharger or a malfunctioning sensor.

Symptoms

• Check Engine Light is on

• Reduced engine performance

• Possible engine knocking or pinging

Common Causes

• Faulty charge air pressure sensor

• Turbocharger overboost condition

• Blocked or restricted air intake

Glossary

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

Turbocharger: A device that increases the engine's efficiency and power by forcing extra air into the combustion chamber.

Diagnosis steps

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

• Inspect the charge air pressure sensor and wiring.

• Check the turbocharger for overboost conditions.

Repair procedures

• Replace the charge air pressure sensor if faulty.

• Repair or replace the turbocharger if overboosting.

• Clear any blockages in the air intake system.

Tools required

• OBD-II scanner

• Multimeter

• Wrench set

Estimated repair cost

$150 - $600
