Code P1457 Acura Description
The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two-way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two-way valve to the fuel tank). There is 0.04-inch leak detection and 0.02-inch leak detection. If the 0.04-inch leak detection results are OK, the 0.02-inch leak detection runs. The Diagnostic Trouble Code (DTC) P1457 is detected when the EVAP system has a very small leak.
