when I go up a grade, my gauges and dash sensors go crazy. Why?

Asked by steviebautista Sep 12, 2007 at 03:13 PM about the 2001 Lexus LS

Question type: Maintenance & Repair

I have a 2001 lexus ls 430. Whenever I go up a grade my rpm gauge goes up and down and all my sensors on the dash light up. When I pull over and turn off the car for a few minutes. It's fine. I took the car in twice to the lexus dealer. They replaced the chip twice and still can't find the problem. It worries me when I have to drive on my long distance trips up a grade. It only happens whenever I go up one.

Sounds like a short which may only be grounding out when the vehicle is going up a grade. I can't believe the chip would cause the issue repeatedly if it has already been replaced. Suggest having them look for a short in the wiring harness.

My LS400 is not running like a V8 should. For the first few years i've had the car it ran great. I use to fool around and drive fast, and when i hit the gas it picked up speed and roared like a V8 should, now it doesn't pick up the speed nor rev up like it used to. What could be the problem? What do i need to fix? 1 Answer

I recently purchased a well maintained 1993 Lexus LS 400, but the battery was said to be a problem. I have only driven it a few times, but I notice when I apply the breaks the headlaps blink. Can this be a symptom of an electrical problem that would explain why the battery was always being drained for the prior owner? I am going to purchase a new high quality battery, but the prior owner told me to keep the + terminal disconnected so it would not go dead. Hmmm :( This does not sound like a practical way to address the problem. Any suggestions? Scott 2 Answers
