Automotive trouble code

p1195 which is egr malfunction. it could be clogged with excessive carbon. well thats what my obd II reader said "egr restriction" exactly.

From elsewhere on FixYa:

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!

P1195 SCP HBCC Failed To Initialize is for barometric pressure circuit, ( boost/map sensor circuit malfunction ) found in
memory.

1.Monitor boost / map sensor voltage readings using the NGS tester and
confirm reading are within specifications. also monitor the sensor
after a hot start to confirm that sensor reading change when EGR boost
sensor solenoid swithes OFF to ON to OFF, when the system is
functioning normaly the the test will only occur once, but if there
is no change in reading due to no opening, closing or blockage of
the solenoid ports, EGR valve port,or within the connecting hoses
the PCM will repeat this test three times. But this does not mean
solenoid doesn't stick occasionally.
2.Inspect boost sensor hoses for water.
3.Inspect boost sensor solenoid for leakage, blockage and/or sticking
caused by rust build-up.
4 Inspect EGR valve "hose" port for blockage.
5.Replace boost sensor if sensor was produced before November 96.
Sensor can be identified by stamped (not molded) in 4 digit code on
the top of the sensor.

Of you changed EGR you need to have computer reset - they don't reset themselves.

P1195 EGR Boost Sensor Circuit

That code is for the EGR boost sensor. It has an open or a short in one of the wires.

For one thing the CEL being on all the time how will you know if something else comes up, short of it running bad or worse. The EGR serves two functions. It lowers NOx and allows for greater timing control. If the EGR is not working and the PCM advances the timing when there's no EGR it can cause excessive spark knock. If the knock sensor doesn't work it can cause severe engine damage. If the knock sensor works and the PCM lowers advance the biggest problem you'll have is polluting.

Hope helped (remember rated this help) Good luck.

The belt shold be checked at 60,000 don't let it go past 100,000 Without replacing you you will be buying a new engine.
