Mazda 3 My 2004 Mazda 3 cruise control surges when it is engaged.

Resolved Question:

My 2004 Mazda 3 cruise control surges when it is engaged. This problem began about a year ago--worked fine until then.
Submitted: 3 years ago.

Welcome to Just Answer. My name is XXXXX XXXXX I will be glad to assist you.

 

There are a couple common issues for your concern.

 

There is a updated PCM computer reprogram which you may have already had don.

 

The other is a faulty VSS (vehicle speed sensor)

 

Here is some information about that. This will be your next step.


Please let me know if you have any additional questions.

Thanks

Drew

 

Symptom and Conditions

Some vehicles equipped with manual transmission and without ABS may
not hold a steady speed and may exhibit a surge condition with cruise
control ON and set to a specified speed.

 

Repair Procedure

Check Vehicle Speed Sensor (VSS). Remove sensor according to WSM
section 05 and inspect for worn or broken teeth at the gear. If
confirmed, replace with new part.

Part Information
G564-17-400A Gear set, driven-speed (VSS)

Thic car has ABS--does that make a difference? In April 2011, Local Mazda dealer removed LF wheel speed sensor and installed new Mazda LF swheel speed sensor. Still surges.
Expert:  Drew replied 3 years ago.

This concern was more common on non-abs cars.

 

I would still suspect that you have a faulty VSS. This is the sensor that the computer reads transmission output shaft speed and is also transmitted data to your speedometer.

 

The VSS is located on the back side lower portion of the transmission (firewall side) just above the rear mount.

 

Thanks

VEHICLE SPEED SENSOR (VSS) REMOVAL/INSTALLATION

CAUTION:

  • Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign material on the connector when disconnecting it.

  • If foreign materials are stuck to the VSS, disturbance by magnetic flux can cause sensor output to be abnormal and thereby negatively affect control. Make sure that foreign materials such as iron filings are not stuck to the VSS during installation.

1. Remove the battery duct and battery cover. (See BATTERY REMOVAL/INSTALLATION.)
2. Disconnect the negative battery cable.
3. Remove the under cover.
4. Disconnect the VSS connector.
5. Remove the VSS.

6. Apply ATF to a new O‐ring and install it on a new VSS.
7. Install the VSS.
