The MJ was idling unevenly and the transmission was shifting like I had my foot planted to the floor yesterday. If I don't keep my foot on the gas when pulling up to a stop, it'll stall. This morning it threw a check engine light, code 24 for the TPS. I looked around online, found some testing procedures and tried em out.
Probing the unplugged connector with the key on, engine off, I got <10Ω to ground, (pin closest to the passenger side) . I got ~4.8V between ground and the pin on both of the other two pins. All grounds were done to the neg battery terminal.
I also bench tested the TPS... It seems alright in that I get ~1500Ω to ~300Ω with a reasonably linear transition as I turn it up. I only tested with a digital multimeter, though.
I'm thinking my issue lies in the fact that I'm getting voltage from the middle pin of the connector. From what I've found online, I should be getting 5V from the feed line (driver's side pin), but I haven't found anything clear about what I should be getting from the signal line back to the ECU (middle pin). My mind tells me I shouldn't be seeing voltage at both points, though.
