It just unbolts but I would also clean the mass air flow sensor. This could also cause a TPS code.

Mazda Protege - 1998 DX 1.5 automatic I got a check engine light ON with P1195 code. What do I need to fix this?


P1195 = EGR (exhaust gas recirculation valve) Boost Sensor Circuit Check the sensor and the wiring/connections to it.


Mazda's also had issues with the vacuum lines to the EGR valve 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 Tech service bulletins and recalls for Mazda!

How do you set up the idle on a '93 Mazda Protege? It was easy to do on the old carburater cars.


Idles are preset ,and not adjustable on fuel injection,but look where the throttle cable attaches to the throttle,and where the throttle sets,there might be a screw with a lock nut,and will allow some setting,but not much,cause the throttle position sensor does this threw the computer.The throttle position sensor is on the throttle,on the opposite side of where the throttle cables attach.If this was helpful,then please rate,thank you.

There can be a misfire too from the cylinders.

An engine that hesitates, stumbles or misfires when accelerating or when it is under load is an engine that is either sucking too much air, not getting enough fuel or misfiring. If the Check Engine Light comes on, you may find any of the following codes:

• P0171, P0174 Lean fuel condition codes
• P0120 to P0124 Throttle position sensor codes
• P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR related codes

If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.

Another common cause is dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your scantool. If the numbers are high, it tells you the engine is running lean and the injectors need cleaning. Treat mild cases with a high quality fuel-injector cleaner additive. Severe cases require professional cleaning equipment.

Also if this sensors apply to your vehicle, camshaft sensor or crankshaft sensor if sensors bad you don't get any spark. Also run a scan on the car.

Good luck and rate this solution, please.

Obd2 code p0300 on mazda protege 2002


Just had one of these with a maxima, the code is multiple random misfire, when a misfire occurs, to start is do the basics, replace the plugs, check fuel pressure, clean throttle body, and coolant is topped up. also I have seen if the O2 sensor is not working correctly is can cause a misfire, you will need a scan tool to look at what the O2 sensor is doing, o rby back probing the sensor (don't damage the O2 sensor wires). If it wires replace them as well, if it has coils they usually dont give that code if one fails, it will pinpoint that a certain coil if one fals.
