When a Stellantis 2.4L Tigershark engine triggers a P2135 throttle correlation code, many shops simply swap the throttle body. At The Car Conservatory, our deep-dive diagnostics revealed a systemic mechanical root cause: a stuck mechanical PCV valve. This failure allows intense manifold vacuum to aggressively pull liquid oil backward, fouling the sensitive internal electronics. Read our case study to see how we fix the limp mode condition while completely preventing a costly,
