How to Fix P1195 Error Code on 1997 Mazda Protege: Causes, Diagnosis & Solutions

Model: 1997 Mazda Protege Fault Code: P1195 Posted: 2009-01-19 15:29

I recently replaced the Powertrain Control Module (PCM) in my 1997 Mazda Protege, and all error codes disappeared except for P1195. I'm not a professional mechanic, but I've done some research using my Haynes manual. Can someone explain what P1195 means and what steps I should take to fix it? Specifically, what components need inspection or replacement? I'd appreciate clear, beginner-friendly advice that doesn't require advanced technical knowledge. Thank you in advance for your help!

P1195 refers to the EGR Boost Sensor Circuit fault. Start by checking the sensor itself and all wiring connections leading to it. While this information might not be clearly listed in the Haynes manual, it's a common issue on models like the 1997 Mazda Protege. Ensure the sensor is properly grounded and that there are no loose or corroded wires. A simple voltage test can confirm if the sensor is functioning correctly. If the sensor checks out, inspect the EGR valve and related vacuum lines for leaks or blockages.

Mazda's also had issues with the vaccum lines to the egr and the ports in the throttle body plugging up! I think some models even had a recall so it may be worth checking with your local Mazda dealer or have your father or you check online for tsbs and recalls for Mazda!
