Ok guys, I have a 94 ls400 with traction control giving error code 41 & 47. I have replaced the TPS 89452-33010 (driver side). I'm getting 5 volts to each TPS from the ECU. The car will give no problem if I accelerate very slowly. If I accelerate above normal then I encounter hesitation around 1900 thru 2200 RPM. The only way I can drive through this is by light acceleration. If I’m aggressive then it will not do anything. If I clear the codes then sometime the car will run just fine for a day or two. I have checked all vacuum lines visible and re-cut the ends to make sure there are no leaks. I followed the spec’s for testing the TPS and it looks like the old sensor is good. A local mechanic is leaning toward a new ecu but I disagree because I’m getting 5 volt to both of them. Please help, this has been going on for three weeks and I don’t want to give up and send it to the dealer. Very expensive for my budget.
