Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point - plus a 12-month unlimited...
Catalytic Converter Failure
Most affected vehicles
Toyota Passo X, X L Package, PLUS HANA (2004-2024, 1KR-FE)
Failure mileage range
80,000-150,000km (50,000-93,000 miles)
Typical failure window
Root cause
Imported fuel quality variance and age-related substrate breakdown cause CAT blockage, restricting exhaust flow and reducing power.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - CAT Cleaning | £300 - £500 | £200 - £350 | Chemical cleaning of catalytic converter substrate | Temporary fix; often fails within 6-12 months on high-mileage imports |
| Intermediate - CAT Replacement | £800 - £1,400 | £500 - £900 | Fit new or reconditioned catalytic converter unit | Permanent solution but costly; may not address underlying engine wear |
| Full Replacement - Rebuilt Engine | £1,500 - £2,500 | £800 - £1,200 | Supply & fit rebuilt 1KR-FE with new CAT, upgraded components | Best value for high-mileage imports; includes 12-month warranty |
Our recommendation
For Passo imports over 100,000km, a rebuilt engine often represents better long-term value than repeated CAT repairs. We recommend getting quotes for both options before deciding.
