Question about 2007 Suzuki Forenza Sedan

1 Answer

My 2007 Forenza engine light came on 3 months ago - the transmission was slipping. I took the car over to Suzuki they replaced a sensor for 300 bucks. Worked fine - till yesterday, same thing - it came on again. It comes on steady, not flashing. I have heard that his car has problems wit its engine light coming on OBD-II sensor, transmission... I had two rear tires replaced at around the same time - and the mechanic there (it was Goodyear not Suzuki) accidently broke off some sensor back by the rear wheel or in the wheel well. It's black plastic and about two inches long - he gave it to me - said he was sorry and I could have any Suzuki dealer put it back on. Seemed to imply it wasn't a big deal.

I would like to confirm One Detail from you. When you got the Engine Light 3 months ago, have you Scanned the Car for Error Codes. Engine light indicates that there is a problem in the car. We always advise the customers to take the car to the Auto Zone to get it Scanned for Codes and once you have the codes, it is easier to fix the problem rather than troubleshooting the whole car and replacing components that should not be replaced.

If you have the Car Scanned, kindly tell me the codes so that i could guide you. If not, get the car scanned and let me know.

For your information, i could tell you, Yes, this Model do have some transmission problems. Most of the times, Torque converter is at fault.However, as i said, i hate to comment before i could get the Codes. There might be ample reasons for transmission problems and hit and trial method is never a Good Method on there Models.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Transmission Range Sensor - Suzuki Forenza 2006 All You Need To Know
Symptoms: One day, you get in your car, put it into reverse ... and it sort of SLAMS into reverse. You may also notice your service engine light is on. Then, when you put it into drive, it sort of SLAMS into drive. And then, it struggles to get going ... and probably will not go into the higher gear ensuring you obey the speed limit on a 55 MPH highway (or blow your engine if you try to push it).
Codes: If you have an auto shop hook you up to their machine to read the codes - first, it will cost you about $100 - second, the codes will most likely be P0700 and/or P0705.
Problem: You need to replace your Transmission Range Sensor (part #: 37720-86Z01)
Transmission Range Sensor for a 2006 Suzuki Forenza
Option #1: Take it to a Suzuki dealership and let them replace. All said and done, you should be looking at a price tag around $300.
Option #2: Buy the part and fix it yourself.
• You will NOT find this part anywhere online or in stores. You can ONLY purchase it at a Suzuki Dealership. Cost is just under $50. (this is true as of 24 Dec 2009)
• You can replace this part if you want. But if you break something every time you pick up a tool ... pay the $300 or find a friend who can help.
Instructions to Replace the Transmission Range Sensor on a 2006 Suzuki Forenza
1. Locate the TRS. Open your hood, and look down to the right. See pictures below. That stupid black hose is going to irritate you. I'm not a mechanic. I didn't feel safe taking it off. Looks like it's connected the radiator
2. Loosen the bolt listed as bolt #1 below. You will need a 12mm wrench. I couldn't get a ratchet in there.
3. Loosen bolts listed as #2 and #3. You will need a 10mm wrench for these.
4. Now remove the metal piece attached with bolt #1, and then, remove the TRS. This is a frustration point. Mine did not simply slide right off. You'll have to work them a bit.
5. Disconnect wiring cable. You can do this first or last ... whichever you think is easier. Wiring cable location is noted below. I broke some of the plastic housing here. But, it did not affect the functionality. You're just going to have to figure this one out. This piece will also NOT slide right off.
6. In order to get the TRS back on, the grooves in the center hole (where bolt #1 is) need to match up with the old TRS. The inside of that circle rotates.
7. Final Step - put it all back on. Good luck! I hope this has been helpful for you.
HERE IT IS ...Below the hose
Bolt #1 ... 12mm
Bolt #2 ... 10mm
Bolt #3 ... 10mm

Engine light on It is a suzuki forenza 2007, and never replaced battery (maybe this is the problem)

If your vehicle is starting fine it shouldn't be your battery. The check engine light on all, or atleast most vehicles is because of an emissions problem.

Myself, I would do the following 3 things first;
1. Make sure you have a clean air filter.

2. Have the MAF, ( mass air flow ), sensor checked.

3. Have the oxygen sensors checked.

All 3 of these things can prevent the vehicle's computer from determining the proper fuel/air mix ratio.

I hope this helps you.

The check engine light came on in my car the other day. This is a 2007 Suzuki Forenza. I took it to Auto Zone, and they ran the codes, which said that the engine was running cool. It didn't come up with...

None of that can be answered here

You need to go to a repair shop, that has the proper
scanner to read the codes, and is experienced in
diagnosing the issues
You also will have to spend whatever it takes,to
find a solution. Then you decide what to authorize
and whether you want it repaired
You need to be in the service bay, and shown proof
of any necessary repairs

Take it back,they checked nothing, before they sold it to you. That's what they do. Next time, buy from a private party, and learn to do all your own repairs,you'll never have a vehicle issue again.

On my 2007 suzuki forenza the check engine light came on. i had it troubleshooted at autozone, and the computer indicated the transmission range sensor out of position. where is it located?

no such code on that car, auto zone uses global testing which pulls universal codes, so that code means someting different for the suzuki, need to have it checked by the dealer or a shop that has import software, or post the code # and i can translate it into import code, good luck.

I have a 2007 suzuki forenza that has atransmission problem can only drive in 3rd gear. On the dash has a D in a box with a slash trhu it. What is the problem

My wifes car is doing the same thing. Had the code pulled from the OBD II port and it gave me two codes: PO700, and PO705. Both codes pertain to a TRS (Transmission Range Sensor). Suzuki has an 84 month/ 100,000 mile powertrain waranty. Take it to the dealer and talk to them about the situation. The thing about Suzuki is that their transaxles (transmissions) are none-serviceable

Transmission or Engagement issue?

I had the same problem with my 2006 Forenza - the problem was the transmission range sensor. If you look under the hood, on the drivers side, you'll see your trans. cable connected to a round part that also has an electrical cable coming from it. That is it. Part costs $36.07 at (search for Neutral safety switch in the mechanical catalog).
