Diagnostic Aids
WARNING: This page is about a different car, the 2006 Suzuki Reno and 2006 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
Although this DTC is considered a type A diagnostic, it acts like a type B diagnostic under certain conditions. Whenever this diagnostic reports the system has passed, or if the battery is disconnected, the diagnostic must fail twice before setting a DTC. The initial failure is not reported to the diagnostic executive or displayed on a scan tool. A passing system always reports to the diagnostic executive immediately.
Check for the following conditions:
- Missing or damaged fuel cap
- Missing or damaged O-rings at fuel vapor and EVAP emission purge line canister fittings
- Cracked or punctured EVAP emission canister
- Damaged source vacuum line, EVAP emission purge line, EVAP emission vent hose or fuel tank vapor line
- Poor connection at ECM. Inspect harness connectors for the following conditions:
- Backed-out terminals
- Improper mating
- Broken locks
- Improperly formed
- Damaged terminals
- Poor terminal-to-wire connection
- Damaged harness. Inspect the wiring harness to the EVAP emission vent solenoid, EVAP emission canister purge valve and the fuel tank pressure sensor for an intermittent open or short circuit.
- Kinked, pinched or plugged vacuum source, EVAP emission purge or fuel tank vapor line. Verify that the line are not restricted.
