1994 ls400 tps problem Bad caps now what
hey guys. I just picked this up on Friday and I am trying to work some bugs out of it. The car runs great until I give it more than half throttle after half throttle it starts to buck and check engine light comes on. Code 41 TPS sensor. Replaced TPS sensor and same problem. No change. I connected a scanner to it and after half throttle it drops to 0. Before it slowly goes up from 0 to 24 and then back to 0. Has anyone ran into this before? ecu maybe? I looked at the pins and the wiring and see no problem. Help please

Well I just back probed the ecu and the reading are right going into the ecu. So that means it is definitely the ecu. Now the question is should I open up the ecu or just send it off to be repaired?

Send it to Driftmotion for a rebuild or replace it all together with a eBay or pick'n'pull ECU. Thanks for updating this!
