It’s a step of the process you have to go through to fix a code by applying a simple solution before going for an expensive one if it is not fixed. Solution 1 Tighten the gas cap and clear the codes, (They came back approximately 4-5 restarts later). Solution 2 If the cap was leaking, then Clean and grease the gas cap’s seal and clear the codes. The result was the same as Solution #1 Solution 3 If above method didn’t work then purchase an OEM aftermarket gas cap, don’t try to put a low-quality cap, it will not fix the problem. Solution 4 Sometimes the new seal cap wouldn’t fix the issue, after a few days the light came back with the same issues then what you have to do. Find the original cap from aftermarket and make sure it has an original seal cap swapped the new seal onto the original cap and voila! Problem solved After any of these fixes, you’ll need to clear the codes from the computer. You can either use your code reader to do this the easy way, or disconnect your battery for 10 minutes or so. Frequently Asked Questions: What Is Toyota Dtc C1201 Means?
