TPS adjustment
I don’t have the harness breakout tool but I need to adjust the new throttle position sensor on my car. I really don’t want to hack into my wiring loom.
Any one have a tip for doing it without the harness breakout tool? Went to order one from mid America but it’s out of stock. My car is a 1991. Thanks, Reed |

Re: TPS adjustment
A decent setting can be obtained by setting it midway between the limits, which places the TP Sensor horizontally level.

Re: TPS adjustment
It’s possible to rig a set up to get the setting.

Re: TPS adjustment
You guys should just spring for an inexpensive Android tablet and $35 for ALDLdroid along with an ALDL connector. U’ll use it over and over and over again.

I’ve got the tps in now by just centering the bolts. All ready drives better than before, but I’d like to get it adjusted properly. |

Re: TPS adjustment
I got a aldl android set up and I was going to use it to set the TPS voltage.
I've never used scanner before so this is going to be a stupid question but are the volts the top value on my data log? If not, how do I get the app to show tps voltage?Screenshot_2019-12-22-16-14-42.jpeg Sent from my SM-T280 using ZR-1 Net Registry mobile app |
