FUEL TANK PRESSURE MONITOR
| TLT | CID | Unit Conversion | Description of Test Value | Description of Test Limit |
|---|---|---|---|---|
| 1 | $01 | Multiply by 0.0916 [mmHg] | Test value of 0.04 inch leak from fuel tank: Determined by fuel tank pressure change | Malfunction criterion for 0.04 inch leak from fuel tank |
| 1 | $02 | Multiply by 0.0916 [mmHg] | Test value of 0.04 inch leak from canister and purge line: Determined by canister pressure change | Malfunction criterion for 0.04 inch leak from canister and purge line |
| 1 | $03 | Multiply by 0.0916 [mmHg] | Test value of EVAP VSV: Determined by pulsation of canister pressure change generated by EVAP VSV operation | Malfunction criterion for EVAP VSV |
| 1 | $04 | Multiply by 0.0916 [mmHg] | Test value of pressure control valve (VSV for vapor pressure sensor): Determined by pressure difference at switching over pressure switching valve | Malfunction criterion for pressure control valve |
