Default Throttle Position Sensor

The TPS adjustment is supposed to be
0.45 volt on my CRV 2003.
But the lowest voltage I am able to get is
1.6 volt.
I am puzzled.
What makes this happens?
The TPS is new.

I just got a bluetooth OBD2 scanner and the TPS reading shows 33% with the throttle closed. It should read near 0%.
So the problem is a higher voltage input.
It is an electrical problem.
Someone in a forum mentionned a similar problem was solved by fixing a faulty ground on the car ECU. How to troubleshoot this now?

you will not get a zero reading on a TPMS sensor through a scanner. The throttle is not completely closed and will always remain or certain percentage open. I would have to go and check mine but usually shows about 9% opened 33% seems high ( like at a high speed cruise high).so you should check the input voltage the other information that I gave you on that troubleshooting website. Of course you should verify that the throttle is as close as it can be

The input voltage is normal at 5 v.
The ouput voltage is 1.6 v. at idle. This is the lowest I could get when I calibrated the TPS.
I could not get 0.5 v. and I don't know why.
This is a new TPS. I had the same readings with the old TPS. So it doesn't look like it is a TPS problem.

I have read that the TPS output wire circuit could be energized by the ECU. Fault.
That voltage is added to the TPS output resulting to an higher voltage. The throttle opening shown by the ECU is then faulty and this brings extra fuel consumtion and other problems. My case.

I am having an issue with my TPS, but mine has 6 pins and no obvious way of rotating it to adjust the voltage. can anyone let me know how to test the sensor? all the info I can find is for a TPS with a 3 wire plug. This is an Australian produced 12/2004 CRV:HONDA CRV Manual RD RD7 12/2001~01/2007 4 Door SUV 4WD PETROL 2.4 litre, K24A1 I4 16v DOHC VTEC MPFI {118kW}
Symptoms: loss of acceleration, engine light on. Fault code: P2138 (TP or APP sensor voltage correlation)
Troubleshooting: If I pull and reinsert the LAF fuse, I regain the ability to accelerate.(I found this out when I thought it was an issue with the O2 sensor/s, before I got and ODB2 tool).
I have cleaned all the connectors on the TPS and APPS and also tested voltages on the APPS (which were good), but dont know how to test this 6 pin TPS.

Please help if you can!
