If you own a Flex Fuel Toyota Tundra, you might have encountered hard starting, rough running, and poor fuel economy due to a high alcohol fuel density level. Dealerships often charge a hefty fee to address this issue, but a Cheap Scan Tool Capable Of Ecu Reset can provide a DIY solution. This article details how a Launch X431 CRP919E bidirectional scan tool successfully reset the alcohol fuel density level on a 2013 Tundra, resolving these common problems.
Launch X431 CRP919E: A Budget-Friendly Solution
The Launch X431 CRP919E offers a cost-effective alternative to expensive dealer repairs or complex software solutions. While a Technical Service Bulletin (TSB-0166-19) outlines a fix for this issue, dealer costs can exceed $1200, with potential for the problem to reoccur. Some Tundra owners have attempted using Techstream cables with unlicensed software, often encountering compatibility issues. The CRP919E, however, provides a straightforward and reliable method for resetting the fuel density learning value.
