Frequently Asked Questions about P0722 Suzuki Code

1. What does the OBDII code P0722 mean on a Suzuki?

The P0722 code indicates that the transmission control module (TCM) is not receiving a signal from the output speed sensor, which monitors the rotational speed of the vehicle's output shaft.

2. What are the common symptoms of the P0722 code on a Suzuki?

Symptoms may include erratic or delayed shifting, the check engine light turning on, poor acceleration, or the vehicle going into "limp mode."

3. What causes the P0722 code to appear on a Suzuki?

Common causes include a faulty output speed sensor, damaged or corroded wiring, a loose or disconnected sensor connection, or a malfunctioning transmission control module.

4. Can I drive my Suzuki with a P0722 code?

Driving with a P0722 code is not recommended, as it can cause further damage to the transmission and affect the vehicle's performance and safety.

5. How do I diagnose the P0722 code on a Suzuki?

Diagnosis involves scanning for codes with an OBDII scanner, inspecting the output speed sensor and its wiring, checking for loose connections, and testing the sensor with a multimeter.

6. How do I fix the P0722 code on a Suzuki?

Fixes may include replacing the faulty output speed sensor, repairing or replacing damaged wiring, cleaning corroded connections, or reprogramming or replacing the TCM if necessary.

7. How much does it cost to repair the P0722 code on a Suzuki?

Repair costs vary, but replacing the output speed sensor typically costs $100–$300, including parts and labor. Wiring or TCM repairs may cost more depending on the damage.

8. What tools are needed to fix the P0722 code on a Suzuki?

You will need an OBDII scanner, a multimeter for testing the sensor and wiring, and basic hand tools for removing and replacing the sensor.

9. Can a bad output speed sensor damage my Suzuki’s transmission?

Yes, if left unresolved, a faulty output speed sensor can lead to improper shifting and increased wear on the transmission components over time.

10. Will clearing the P0722 code fix the issue on my Suzuki?

Clearing the code will turn off the check engine light temporarily, but the underlying issue must be resolved to prevent the code from returning.

Discuss the causes and fixes for P0722 Suzuki OBDII Code

  • Except my speedometer is working fine so what the heck?

  • The code means that at some point the sensor didn't sent the signal. If everything is working fine, then just clear the code.

  • 06 Suzuki aerio. Upon first acceleration to highway speed everything works fine. The transmission shifts at the proper time nice and snug not too soft not too hard. Upon 2nd acceleration from a stop stuck in 3rd gear. Shifting through the gears manually works fine except overdrive does not engage or even try to. Restart the car and all repeats. Absolutely no noticeable glitch in the speedometer or rpm gauge. My theory is if the computer can tell the spedometer how to display accurately then why does it shift improperly and why set the code?

  • The speedometer uses the Vehicle Speed sensor to determine the vehicle speed. The P0722 code is for the Output Shaft Speed Sensor. Different sensors

  • When I unplug the output shaft sensor the spedometer does not work. I only see one sensor when searching for parts & in the diagrams and whatnot. This link is the sensor that I am unplugging. http://www.rockauto.com/en/...
    Maybe it's working halfway and that's the issue.

  • I recently changed the transmission range sensor (TRS) because thats the code it was giving at first. But it still kept jerking when changing gears and high rpm's .pulled the code again and still it was TRS . Didnt drive it much for a while and started driving again and now the speedometer isnt working and still jerks but is now saying it is the speed sensor no signal. Do u think the trs i put on was faulty or do i have 2 problems here

  • the sensor for the speedo was fine. it was the speed sensor for the trans ecm that was the problem. it was not plugged in all the way.

  • yes thanks for the tip. you caused me to find the other sensor and discover it was not plugged in all the way.. problem solved!

  • Thank you letting us know and I'm glad you fixed the problem.

  • P0722 code
