Error Code P0335 and Solution
----
Just wanted to share a cause for error code P0335 and a simple solution. A few mornings ago, all of sudden, my car wouldn't start. When I pressed the Start button, I heard a click sound as if the starter solenoid pushed the plunger to engage but the the starter gear wouldn't turn. My first thought was that it must be a weak battery, because it was a typical behavior of a weak battery. However, my battery was fairly new, a genuine OEM National battery made in Japan from Lexus dealer. I tested the battery anyway and it was indeed in good condition. I tried a number of times to start the car but got the same one click sound. I then noticed that the VSC message came on the dash. I connected Techtream to the car and got an error code P0335 with the explanation that "Crankshaft position sensor A circuit" was not functioning properly. My first instinct was to order a new sensor and replace the one on my car. Then, it occurred to me that the battery on my fob key had not been replaced for more than a year. Could it be that a weak car key battery didn't communicate well with the car and caused the problem? I replaced the key battery and cleared the error code P0335 with Techstream. With the new battery in the car key, I pressed the Start button. The car started without hesitation and the engine ran smoothly. Everything sounded and felt normal. Since then, I have driven more than 200 city-stop-and-go miles. I have been able to start the car without a problem and the engine has been running without problem. The error code P0335 has not shown again. My conclusion is that a weak battery on the car key can cause a seemingly starter-associated problem and can also trigger a false error code P0335 (Crankshaft position sensor is bad). Before replacing the car battery or the starter or the crankshaft position senor, replace the car key battery first and it can be all you need to do to fix the problem.

I assume that you meant the car key battery. For fob key, the battery size is 1632. Any brand of battery of this size should work and you may purchase it from Walmart, Target, and most stores that sell cell batteries. Personally, I prefer Energizer or Duracell brands as they tend to last longer. I buy batteries from Amazon and I always keep a spare 1632 battery on hand since I have four Lexus keys that use 1632 battery, just in case that one of them need a new battery. If you meant my car battery, I have a National/Panasonic white-color OEM battery made in Japan and I permanently "borrowed" it from my GX 460 which I purchased brand new from my local Lexus dealer.

VSC warning messages may suggest all kinds of trouble codes and may also flag brake system issues. In the situation I described here, it is solely associated with Error Code P0335. Don't want to mislead you or others.

You are so right and couldn't agree more. It is a simple procedure to replace the fob key battery and it took just a couple of minutes. No tools are needed. Just pull out the physical key from the fob key and use it to jack open the key case. No need to go to the dealer for it unless it is covered by warranty and free of charge.

I didn't pay attention to the dash display after turning the engine off the previous night. Maybe there was a warning message about low key battery that I failed to take notice of.

I have a 2008 ISF. Sort of the same happened to me. The behavior when starting was the same. The check engine lights came on and it threw the same code. There was no low battery light. I put in a fresh battery in the remote but it still wouldn’t start. I jumped the car, it started but code remained. Battery died a couple hours later after not driving. Jumped it again. The battery tested bad. Was only 1 year old so I was able to get a new one under warranty. After the new battery was installed, there was no more code. It’s been working fine for a week now.
