2006 Chevrolet Cobalt P1182 Diagnostic Trouble Code: What Does It Mean and How to Fix It?

Model: 2006 chevrolet cobalt Fault Code: P1182 Posted: 2014-02-19 11:24

I'm wondering if replacing both oxygen (O2) sensors will resolve the check engine light issue. Additionally, I've recently received a P1182 code — can someone confirm what this means and whether it's related to the 2005 model or similar years? Note: The P1180/P1182 codes are associated with issues in the intake manifold pressure sensor (SCIP), not oxygen sensors. This is a known issue specific to certain 2006 Chevrolet Cobalt models, though there is no official recall. There is, however, a Technical Service Bulletin (TSB) available for technicians that outlines repair procedures. Important: A TSB is not a free repair and does not guarantee fixability without proper diagnostic tools. For accurate diagnosis, a scan tool with freeze frame data is recommended to capture real-time vehicle conditions during the fault. For DIY owners, one possible troubleshooting step is to inspect vacuum hoses connected to the bypass valve actuator and clean the throttle body (TB). Avoid using aftermarket parts such as K&N filters, as they may interfere with sensor readings or cause false codes.

I own a 2006 Chevrolet Cobalt and my check engine light has not turned off. I searched the official recall database for Chevy Cobalt models and found a P1182 diagnostic code listed. Can you confirm if this is the same issue as in the 2005 model or if it's specific to later years? Is there an official recall for this code?

P1182 refers to a problem with the Intake Manifold Pressure (SCIP) sensor. There is no official recall issued by Chevrolet, but a Technical Service Bulletin (TSB) exists for technicians. A TSB provides repair guidance and does not cover free repairs — it's only applicable when performed by certified professionals. To properly diagnose this issue, use an OBD2 scanner with freeze frame data to capture the vehicle’s real-time performance during fault conditions. For DIY troubleshooting: Inspect vacuum hoses near the bypass valve actuator. Clean the throttle body (TB) thoroughly. Remove any aftermarket modifications such as K&N air filters, which can interfere with sensor readings and cause false or persistent codes.
