What is code p1195 - 2000 Dodge Dakota Quad Cab

P1195-,Catalyst monitor o2 sensor 1/1 slow response

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!

Try a full reset. Disconnect the car battery for about an hour. Reconnect the battery then try it again. Doing a full reset should reprogram the EEC to go back to factory settings. It worked doing this on my Ford. I would suggest it will work on a Mazda.

P1195 refers to the map sensor, not the egr solenoid. It could be a bad map sensor, bad wiring, or possibly a bad or loose vacuum hose.
P1522 refers to the air control flap actuator on the intake manifold. You can see about yhat at the link below.

P1170 HO2S Bank 1 Sensor 1 Circuit Fixed (Bank 1 Sensor 1) The ECM (engine control module) is getting a low or no signal from the front oxygen sensor on bank #1. Possible bad sensor or open sensor circuit.
P1195 EGR Boost Sensor Circuit There is a problem with the EGR (exhaust gas recirculation) system. Possible plugged or restricted passage or sensor / sensor circuit problem.

P1195
Barometric pressure (EGR boost) sensor circuit malfunction
p1522
Variable resonance induction system (VRIS) solenoid valve #2 circuit malfunction
P1777
Torque reduced signal error (ECT sensor)
P1792
Throttle position sensor (TPS) malfunction

Thats a lot of sensors to fail at once i would check out the wire connected to your computer or maybe the computer itself...

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.
