[H.xterra]

Hi guys, I have an xterra 2007 code 1705 tps.It caused problems for shifting gears.Does anyone know about this problem?I fully depress the accelerator pedal and it doesn't accelerate.I waste a lot of fuel.I would be very grateful if you could help me find this problem.

The code points to the Throttle Position Sensor (TPS). A bad TPS will cause shifting and acceleration issues.

This is usually caused by a bad connection with the TPS, broken harness, or a bad TPS (bad TPS is probably the most common).

I would start by unplugging and re-seating the harness connector to see if it's just a bad connection (do this with the vehicle off and the keys out of the ignition. Also inspect the wires in the harness near the TPS connector to make sure they are not broken.

From there you can either test the TPS as per the FSM (I recall you've been given the link before):

If needed you will have to replace the TPS. If you do so, you will want to go through the re-learn process in the FSM.

Also check for excessive carbon build up in the Throttle Body. This can prevent the butterfly from actuating correctly. Be careful doing this as it is an electic TB. It should be disconnected for cleaning and ideally removed from the vehicle. If left connected there is the possibility of the TB actuator closing it on your fingers and some TB's are strong enough to cause pretty severe injury. (removal of the TB from the vehicle is best as it will also prevent the carbon from being flushed down into the intake/engine.

My son's Mitsubishi Outlander has had this code a few times over the last 10 years. The first was cracked wire harness insulation to the TPS causing shorts. The second was a bad TPS. The most recent was due to the Throttle Body. It ended up being too much carbon in his 18 year old TB that was preventing the TB butterfly from actuating properly. A quick removal and cleaning had him back up and running.

So, start with
1) wire inspection
2) re-seating the TPS connector (a little dielectric grease never hurts)
3) re-seating the connector to the TB actuator (If this seems to solve the issue short term, you likely need to clean the TB)
4) test the TPS as per the FSM. Replace and re-learn if bad.
5) Remove and clean the TB. Try to use electric TB cleaner or electrical component cleaner as it may come into contact with the electrical component of the actuator. Regular carb cleaner is not typically recommended for electronic TB.

^^^ not this

On a 2007 the TPS is read by the ECM and this information is sent via CAN to the TCM. P1705 is a TCM code which means that one(or more) of the following things is happening;

1) there’s more codes that you aren’t sharing
2) no communication between ECM and TCM
3) you haven’t read NTB10-003 that gives a specific diagnostic procedure for this code
4) you had water in your transmission and didn’t fix it properly.

The things you talk about are all good.🤕

Thank you very much. I will try to implement these actions at the right time

 

[Blackberry]

Good luck

I would trust Blackberry's take on it. He is a Nissan Mechanic and has training and a lot of experience with the gen2. My only knowledge of the gen2 is from the things I read here and my comments were based on another vehicle from another manufacturer. The systems could be very different.

Of course, there is no harm in checking your connections etc, but if there are any other codes please share them. Some readers will only give the P codes, but don't read transmission codes etc. There could be codes that you are unaware of.

Has the radiator been changed in the past? The water in the transmission that Blackberry speaks of would be due to the faulty radiator issue in the gen2 up to around 2009. It's possible that whom ever owned it before you experienced this failure before you owned the vehicle.

 

[Blackberry]

If you did replace the control valve(which includes TCM) it may need to be programmed to operate correctly. The bulletin is pretty clear and addresses that code specifically. Check power and ground connections to TCM, if they are good then replace the control valve. Factory parts come blank and need to be programmed to operate correctly.

Hey Blackberry, could I ummm...come apprentice under you!😃 I'll pay!

I replaced my car ecm two months ago.The vin number of my car does not match the vin number of my new ecm,is that recommended?Since then, it has been providing this code.

 

[Satito]

Once again, I'm sure that Blackberry will have more insight into this, but here is some generic info that applies to most vehicles.

I noticed that you have an Iraq flag in your profile. Is that where you are currently located? Is there a Nissan dealership near you?

I think that if the code appeared specifically after you changed the ECM then it is most likely that the issue is with the ECM. If a new code shows up right after you make a change, you should go back and trouble shoot the change that was made.

If the ECM isn't programmed correctly it can send incorrect info to the TCM, which can cause shifting issues, power issues, and engine revving or stalling.

As Blackberry noted, if you changed the TCM it may need to be programmed. This is likely the same case for your replacement ECM, especially if it was a used ECM from a vehicle of a different year and or trim level. The software versions in the ECM and other systems such as TCM need to be compatible. Parts from different years may not have compatible software and may need updating to work.

Yes, I live in Iraq, but there are no Nissan dealers here. Everything is bad there, mechanically and electrically. I have to talk to you because I can't give my car to people who don't know anything.

Was the replacement ECM new or used?

Do an internet search for Nissan Iraq. I'm getting a fair number of hits complete with a map. Here's the listings my search pulled up. I don't know what part of the country you are in or the current situation with regard to traveling, but there appear to be service centers in Erbil, Baghdad, and Sulaymaniyah. The photos with the listings show pretty standard Nissan dealerships and service departments. I'm sure that some of the other companies listed also have a service department.

I've used the ecm and reprogrammed it. Thank you very much for your efforts.

 

[Blackberry]

If you reprogrammed it then why wouldn’t you write the correct VIN at the same time. None of this makes sense.

How am I supposed to earn any points like this

 

[Satito]

Try to post a point by point list of all the things you have done to the vehicle since before the problem started. The more info we have the more likely we can help. We need all the pieces if we are going to complete the puzzle.

I guess you should check all the connections and wire harnesses. Also check the grounds and power as mentioned by Blackberry. If all else fails I think you'll need to take it to Nissan, where they should have the specialty tools to troubleshoot it.

You have checked the coolant and transmission fluid to make sure that they haven't mixed right?

 

[Blackberry]

Oh we’ve been through this already.

Signal gear problem

 

[Satito]

Good memory Blackberry!

 

[Blackberry]

Signal gear problem

actually this might be from a different vehicle. At any rate, I stand behind my previous recommendation. Follow NTB10-003 and most likely you’ll be replacing the control valve w/TCM. This will need to be programmed if a blank part is installed
