Honda Jazz: EVAP Purge Valve Failure - P0496 Code

EVAP Purge Valve Failure - P0496 Code is a common engine fault on the Honda Jazz on the 2014–2020 cars, and we rate it major. Putting it right costs $180 to $450 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 51 documented faults on the Honda Jazz.

What you are looking at

No photograph available

We do not hold a verified photograph of the Intake manifold yet. We would rather show none than show a picture of a different part.

What goes wrong

The EVAP canister purge valve solenoid on GK Jazz L15B2 engines is prone to internal failure leaving the valve stuck open. A failed-open purge valve allows fuel vapours from the charcoal canister to flow into the intake manifold at idle and low load conditions when purging is not commanded by the ECU. This creates an intermittently over-rich mixture at idle causing rough running, stalling, and hesitation. The fault typically stores DTC P0496 indicating EVAP flow during a non-purge phase. Codes may clear temporarily only to return within days.

What you would notice

Check engine light with stored DTC P0496
Intermittent rough or hunting idle when warm
Occasional stalling at idle particularly when the engine is at full operating temperature
Fuel vapour smell from engine bay or through cabin vents
Hesitation under light throttle after a warm restart

How to check it

Where to look. EVAP purge valve solenoid mounted on intake manifold vacuum line, with hose running to charcoal canister under rear of engine bay

Parts involved: Intake manifold.

What it costs to put right

$180 to $450 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the check engine light shown a P0496 or any EVAP fault code?”
“Any intermittent rough idle or stalling, particularly when warm?”
“Has the EVAP purge valve been replaced?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Honda Jazz buyer questions

Is evap purge valve failure - p0496 code serious on a Honda Jazz?

We rate it major and common on the Honda Jazz. The EVAP canister purge valve solenoid on GK Jazz L15B2 engines is prone to internal failure leaving the valve stuck open. A failed-open purge valve allows fuel vapours from the charcoal canister to flow into the intake manifold at idle and low load conditions when purging is not commanded by the ECU. This creates an intermittently over-rich mixture at idle causing rough running, stalling, and hesitation. The fault typically stores DTC P0496 indicating EVAP flow during a non-purge phase. Codes may clear temporarily only to return within days.

How much does it cost to fix on a Honda Jazz?

$180 to $450 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Honda Jazz years are affected?

Our research records this fault on the 2014–2020 Honda Jazz. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Scan for P0496 or any other EVAP-related fault codes. Apply vacuum to the purge valve with a hand pump and confirm it holds without leaking down. Check EVAP hose routing from charcoal canister to purge valve solenoid for cracks or disconnections. Observe idle quality when engine is fully warm.
