My 2014 Ford Escape is exhibiting a rough idle and a noticeable gas smell. I have not driven the vehicle recently due to concerns about potential catalytic converter damage. The car has only 55,000 miles on it. Diagnostic trouble codes P26B7, P0238, P0234, P045
I'm hesitant to dive deep into the vacuum system, as it's complex and potentially risky. I might try testing the sensors related to the turbocharger with a multimeter, but I’m not confident enough to perform more advanced repairs without guidance.
Several reliable posts in this forum discuss root causes for these codes—many point to wiring or sensor failures. A diagnostic multimeter would be helpful here. Please update the community with your findings and any resolved issues.
The trouble codes you're seeing—P0238, P0234, and P0236—are commonly associated with turbocharger-related issues. P0453 relates to evaporative emissions system leakage, while P007D indicates a problem with the fuel pressure regulator. These codes suggest potential sensor or wiring faults in the turbo system. Consider either taking it to a professional shop or attempting a DIY diagnosis using a multimeter and scan tool.
