Question about 1999 Mazda 626
I have a 1999 mazda 626 limited edition.
I would like to know how to find the car code for 1999 mazda 626 edition car code please?
This code does not always mean the O2 sensor is low, but if u want to replace it here is the info to do that and the part number.
The sensor you want is the one in the exhaust pipe of the engine cylinder bank that has #1 cylinder in it, as you face the engine with the hood open the cylinder bank u want is the rear bank, u will need to jack the car up and get under it to remove the sensor, u may also need a special socket to remove it, the sensor is the one that is before the catalytic converter. part number is:DENSO Part # 2344068
REAR; Before Catalyst

Yes, I experienced the same thing with mine... you have to losen the 2 motor mounts on that side and lift the motor up about 3 ". I worked at a garage so I had access to an engine hoist. Try using a jack from underneath. Nice engineering from Mazda!!!

The transmission range sensor aka neutral safety switch is located underneath the air filter on top of the transaxle and very easy to access. Replace this part (around $50) and it will solve your problem.
What happens is this, when your tranny warms up, it disperses heat to the sensor switch and if its faulty or worn out, will send faulty relays to the transmissiom computer module (TCM) and makes the transmission shift irratically (OD to 3rd and back while driving at freeway speeds). You tranny is not overheating like most people believe, its the switch. Mechanics are telling alot of people that their tranny needs replaced. Watch Out For These People!! They only want your money!!

That is right I was haveing the same problem with my 99 mazda 626 with 139,000 miles. It started shifting crazy. Come to find out that alot of the mechanics wanted me to think my tranny was on its way out! But I showed them different. It was the transmission range sensor switch. It cost like $40 at advance auto parts. I tried to clean the original one but the problem came back. So I replaced the swich and the problem is gone! Also they dont call it a transmission range sensor in the parts stores, Its called a Neutral saftey switch! Same thing, but different prices at the dealer and parts stores. The dealer wants $70 dollars for the part!

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.
