Tacoma Spark Knock

Order Reprints

Some 2012-2014 Toyota Tacoma pickup trucks equipped with a 1GR-FE engine may exhibit a spark knock (detonation) during light acceleration and/or uphill in hot weather (80 degrees or higher). The ECM logic has been modified to reduce the possibility of this condition. Reprogram the ECM with the latest available software.
