I find it hard to believe the Mazda dealership can't tell you what the codes are. They made the dang heap .

Try a different Mazda dealership. Most dealerships will not tell you free of charge what a code means. They are going to want to read the codes themselves and charge you for diagnostic time .

Also, the year of the vehicle would be a help.

Sorry, the year is 1996 Mazda You are correct in that the dealership service department said they didn't know, BUT, would be glad to set an appointment , so they could run diagnostics for 75.00.

Correct. The dealer will not give out free information, that is how they make their money! .

Check autolibrary.org for code descriptions, but unless you have a good scanner/software to diagnose the problem, you may just end up changing parts to nail the problem. Check alldata.com for known bulletins/recalls that might come up on the problem/code.

Probable Cause Wiring, HO2S, fuel pressure, fuel system, mechanical fault, Engine Control Module . Joe this is what the code says in the chilton library, also my daughter says she had her oil changed yesterday before this light came on, any possible connection?

Again, why you need a scanner .

Any one of them could cause the problem. Sure, someone could have knocked the O2 sensor wire off changing the oil filter or something, but it's unlikely that is the case.

The scanner tells the tech what is going on and where to start looking (but doesen't solve the problem for him/her). Without that it's like trying to find a needle in a haystack.

You did make sure the gas cap is tight, right???

Code P1170 is for the front 02 sensor, right hand side on a V-6. On the 4 cyl it's the front 02 sensor. The sensor is actually working but the switching rate is too slow. Needs replaced.
If the light came on right after the oil change, check the 02 sensor wiring to make sure that it is plugged in. It could've been snagged or unplugged when the oil filter was removed.

harleyboy, Thanks... I will try that. The Mazda Millenia is a V6. I see 3 O2 sensors under the hood. Just checking to make sure I get the correct sensor(they really cost). Is it the sensor closes to the front of the car located after the manifold?

It's the O2 sensor closest to the manifold, at the firewall.

harleyboy, Do you know why the P1170 code reads ESO-engine shut off slenoid fault on the scanner at AutoZone?

I recently replaced the 02 Sensor on my Plymouth Voyager and I found a good place to buy the 02 sensors online.. Aftermarket sensors only cost about 1/2 the OEM sensors..

check them out here..

I have no idea why Auto Zone lists engine shut off solenoid fault for the code P1170. To my knowledge, I worked at a Mazda dealership for 14 years, there are no Mazdas with an engine shut off solenoid. According to all the factory info that I have available, the P1170 is for the right front 02 sensor inversion rate. How many miles are on your car? Are you having any particular problems? Driveability, fuel consumption etc? When did the light come on and were there any additional codes that were set?
Madza recommends 02 sensors be replaced at 90,000 miles. Any type of contamination or excessive carbon build up can cause both the converter and the 02 sensor to malfunction.

harleyboy, You are very helpful. The mazda has 92,000 miles. No other known problems. The light came on after being park up-hill. Car was hard to put in gear (maybe the way it was parked) after about 2 miles of driving the light came on. Would you know the part number by chance? I was told that all the O2 sensor were different.

No, I don't know the part number but if you ask for the 'right front 02 sensor, closest to the firewall' you should get the right part. If you are standing on the drivers side of the car at the fender, looking into the engine compartment, you will be standing behind the transmission. The windshield will be at your right and the front bumper to the left. The 02 sensor you need is the one closest to the firewall. The front sensors differ in the length of the wire that comes off them that plugs into the wiring harness. At 92,000 miles, and no additional problems, it's probably a needed maintenance item, although an expensive one. Prolonged driving without replacing a bad sensor will eventually lead to problems with the converter, even more expensive.

harleyboy, I changed to 02 sensor and the check engine light came on after 40 miles. It still reads the same code P1170. Do you have any other suggestions?

P1170 is for heated oxygen sensor (Front RH) signal remains unchanged for more than 20 seconds after engine control has entered feedback zone.
Possible causes:
Front RH HO2S Malfunction
Open or short circuit in wiring from heated oxygen sensor (Front RH) terminal A to ECM terminal 31.
Intake-Air System, fuel system, ignition system malfunction.

wsmall7283..... Did you reset the light? How did you do this? Removing the battery cable will not reset the light on OBDII compliant cars.

OE Part number for the oxygen sensor is as follows:
KLA618861 Federal Front on exhaust pipe $180.75
KLC818861A California Front on exh. pipe $236.80
KLD818861 Federal Front on exh manifold $215.35
KL5618861 California Front on exh. manifold $236.80

If you need the numbers for the rear let me know.
Hope this is helpful to ya,
Billy

Small:

A scanner/code reader is required to properly shut off the light.

I had the P1170 code cleared with an OBDII scanner but the check engine light came on after driving 54 miles. Is there a engine shutoff solenoid on the Mazda Millenia?

Sounds like the problem was not fixed (hence the light returns) or there is a new problem.
