SOURCE: code 17 on a mazda 626 1992 lx what does it mean

The OBD-1 two digits trouble codes listed 'code-17' as:
Oxygen sensor.

This means that the fuel and ignition systems performance are in need of attention.

1.Distributor Cap: remove the 3-bolts holding the distriboutr to its body.
2. Inspect the distributor cap for cracks, and the roror-button is not worn or broken.
3. Inspect the distributor-cap terminals are not corroded or charred. Replace if charred. Clean them out if corroded.
4. Check the distributor-rotor for cracks or corrosion on its tip, and lesser spring tension.
Replace as necessary.
5. Reverse steps 1-4 to re-install distributor cap. Be sure to remove and replace the plug wires from the old distributor-cap to the new distributor-cap one-by-one. If not, the engine would not run.

Fuel-Filter:
1. Undo the top clips holding the fuel-filter hose, and undo the lower clips also.
2. Take out the fuel-filter from its mount.
3. Replace the fuel filter as necessary.(please not the way it was mounted) Reverse removal for installation.

SOURCE: how can i fix my mazda 626 transmission range

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!!

SOURCE: 1999 Mazda 626 LX Engine error code 1602

Hi!!
DESCRIPTION & OPERATION Immobilizer system consist of an ignition key (transponder equipped), coil (part of ignition lock cylinder), immobilizer unit, Powertrain Control Module (PCM), SECURITY light, and related wiring and fuses.
This system requires a key that has been programed into PCM and immobilizer unit to operate vehicle. When a key is used that has not been programed into PCM and immobilizer unit, the first 3 times the PCM will carry out fuel cut-off and ignition cut-off operations and engine will stop in a few seconds. The 4th time or after, engine cannot be started.
SECURITY light will illuminate for 1-2 seconds under normal operation. SECURITY light will flash when key ID does not match stored ID and SECURITY light will stay on when code word of immobilizer unit does not match stored code word.
Anti-theft Code 1602 refers to a miscommunication or no communication between the immobilizer system components, if vehicle starts, it means it is an intermittent problem. Most problems in electronic control system result from faulty wiring or poor electrical connections. To avoid unnecessary component testing, perform a visual inspection first.

Airbad error code 47


For a 99 626, the service information says that code '7' is for the passenger side airbag module. I know that your question says that you have a code '47', but the information has codes 1 / 2 / 3 / 6 / 7 / 11 / 12. It states "replace SAS module for codes not listed." The SAS module is the main airbag computer.

P0700 is just to tell you there is a trans code stored . P1794 is a vehicle speed sensor problem or output speed sensor problem depending on the trans type. P0501 is a body computer code for no vehicle speed signal.I would replace the output speed sensor.
