TPS Relearn

[burnout1_ph]

Hello,

Just recently bought a Nissan DataScan II for Android, the software is absolutely fantastic, using it for real time diagnostic for my 2004 Nissan Sentra 1.8. My question is, does the Nissan DataScan have a way to do a TPS Relearn on any of their products that will work with my current vehicle.

Thank you and more power.

TPS relearn is done by the ECU automatically. It doesn't need to be initiated by any external software.

Thanks for the response Tom, I always had issues with the TPS once I removed the throttle body, disassemble everything, cleaned it, and assembled it back, once i start the engine; idle is erratic jumping from 900 rpm to 1500 rpm, I tried resetting the ECU by unplugging the negative battery but that did not work. The only way to fix this is to bring it to the dealer and have this relearn via Consult. Hoping NissanDataScan would have a simpler way of doing this.

Currently using a Gen 1 QG18DE (wired throttle body).

Thanks.

Alfred

Try the Idle Air Volume Learn (IAVL) function. When completed successfully this usually fixes the high idle RPM issue.
