02 ETCS actuator ground location?

Hi guys

My truck has code P1127 set and no throttle response until the mechanical lever kicks in. I think the issue is a loose ground for the actuator. Does anyone have a diagram that shows the location of the grounds for the ETCS circuit/throttle actuator?

Thanks

Re-opening this to see if you ever found a fix? I'm having the same problem and consulted the fix in this thread, but it didn't help. I had no broken connectors but a little oxidation and cleaned it up but same symptom. Very frustrating! https://www.tundras.com/threads/cod...ator-power-source-circuit-malfunction.137914/ Fuse is good. Is there actually an actuator that can be replaced if needed?

 

I highly recommend checking and posting up in this thread: https://www.tundras.com/threads/throttle-body-actuator.130009/

Note: It's SUPER COMMON, as you'll see in that other thread, for A-pillar and cracked/rotten windshield leaks to send water down your wire bundles and either rot out important connections, or get into the fusebox and rot it out (pics & pics & pics, it happens a LOT).

That's the first place I'd be looking, is for traces of water damage. It's been the cause of P1127 on this forum on numerous occasions. I've helped at least a couple people in the last couple of years, @peanut and @elvis233 who traced back to water-entry-corrosion in the connections over by the fusebox.

 

Thanks for the advice - I hadn't come across that thread with my searches.

 

These may also provide some insight:

That last one is yet another case of water down the connector.

It happens a lot.
