P0403 Egr Control Circuit Open at Courtney Szeto blog

P0403 Egr Control Circuit Open. The exhaust gas recirculation (egr) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. The ecm/pcm detects an open circuit condition of an egr motor control circuit for greater than 3 seconds. Corroded or loose connections to the egr solenoid. It’s important to properly diagnose the root cause of the issue in order to effectively troubleshoot and repair the problem. The p0403 code indicates that the engine control module is detecting a series of malfunctions concerning the engine exhaust gas. Some common causes of a p0403 code include a faulty egr valve, a damaged or corroded wiring harness, a malfunctioning egr solenoid, or a faulty egr pressure sensor. The p0403 code is an indication that the engine exhaust gas recirculation circuit (egr). On gm vehicles (such as a 2016 silverado), the p0403 code is stored when: Defective egr vacuum control solenoid (most common) open or short circuit in the egr solenoid wiring. Several factors can trigger the p0403 code, including: High resistance caused by chafing wires, damage to the car wiring harness, an open circuit, or a blocked egr valve. The valve can get clogged.
