Title: Honda Jazz GD1 2005 Throttle Position Sensor TPS voltage
Post by: jazzsport on October 12, 2024, 02:39:30 PM
On the 2nd Oct I cleaned out my throttle body valve as I had both P0507 and P0221 codes, I had to take the battery out so it cleared the engine codes itself and it drove fine for a week but now its back and I suspect it could be the TPS, can anyone confirm the voltage it needs to is:

0.48V @ CT (Closed Throttle) 4.5V @ WOT (Wide Open Throttle)
I found this on another Honda forum and they say its generic for every Honda, can anyone confirm this or let me know the correct TPS voltage.

Thank you.

What is the car actually doing as a result of these errors?

Reason I ask is here….

The high rpm code came up first, but no difference in terms of performance and idle was normal, then on Friday I was suddenly in limp mode, very slow acceleration and when I checked the engine codes the TPS code came up again, idles around 1080rpm according to my obd reader.

Prior to cleaning the throttle valve it was a really hard idle like it wanted to die but I don't get that anymore.

I remember looking at the post you linked but didn't read all the way down as I thought I sorted the problem however I will check for any problems in the wiring now, cheers.

Found it... In quite an awkward spot to fix too :(

It’s some years back now but the mechanic just jumped the break with another wire I think. That fix lasted until the car was scrapped earlier this year. Good luck.
