Fault Codes


Recommended Posts

I have a 91 LS400 but the manual I have is for a 94. when I read out the fault code, it blinks 4 times, then 1. There is no code 41 in the 94 manual. Can anyone help?

I have a 91 Lexus LS 400 and the Airbag Warning light just came on. Please let me know if this is similar to your problem and how you fixed it.

41 is TPS, wiring harness or ECM. My 93 has that code, no cel light, replaced the TPS but still have the code. TPS=throtle position sensor.

Is your car acting up? What is it doing if so?

Mine has slower acceleration and the rpm will drop a few hundred and the car looses acceleration ( kind of like it slips into neutral ) if I accelerate to fast. If I let off the gas and re-accelerate more slowly it is fine but just has slightly less power.
