The Honda P13B is a 1,339 cc, inline‑four naturally aspirated petrol engine produced between 2009 and 2015. It features i — VTEC (intelligent Variable Valve Timing and Lift Electronic Control) on both intake and exhaust camshafts, along with a dual — stage intake manifold. In standard form, it delivers 73 kW (99 PS) and 128 Nm of torque, with its i — VTEC system optimizing efficiency and providing a characteristic power surge at higher RPMs.

The Honda P13B is a 1,339 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (2009-2015). It combines i-VTEC with a dual-stage intake manifold to deliver a responsive, high-revving character and excellent fuel efficiency. Designed to meet Euro 5 standards, it balances urban agility with spirited driving dynamics.

The Honda P13B was used across Honda's FB and GE platforms with transverse mounting. This engine received no major platform-specific adaptations. All specifications are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The P13B is renowned for its reliability, with no widespread, critical failures documented. Honda's internal quality reports indicate very high initial reliability. The primary service focus, as per bulletin A12-018, is managing oil consumption in early builds. No significant failure trends have been reported by VCA or owner groups as of 2024.
Analysis derived from Honda technical bulletins (2009-2015) and VCA owner complaint data (2010-2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The P13B is considered exceptionally reliable. Its simple, naturally aspirated design and robust construction mean it can easily exceed 300,000 km with basic maintenance. The only notable concern is potential oil consumption in pre-2012 models, which is addressed by a known service procedure. Overall, it's one of Honda's most dependable modern engines.
There are no major inherent flaws. The most commonly reported issues are minor oil consumption in early builds (addressed by SIB A12-018), occasional VTEC solenoid failure (causing a loss of top-end power), and intake manifold actuator faults. These are generally inexpensive and straightforward to fix, contributing to the engine's excellent reputation.
The P13B was used in the European-market ninth-generation Honda Civic (FB, 2012-2015) and the second-generation Honda Jazz/Fit (GE, 2009-2014). It was specifically designed for these compact models and is not found in other Honda vehicles, making it exclusive to these platforms.
Significant power gains are difficult due to its small displacement and naturally aspirated design. Basic ECU remaps might yield 5-8 kW, and intake/exhaust modifications can improve throttle response. However, its character is focused on efficiency and reliability, not high performance. Forced induction would require extensive, costly modifications.
Fuel economy is excellent. Expect around 5.8 L/100km combined for the Jazz and 6.2 L/100km for the slightly heavier Civic, translating to roughly 49 mpg UK and 46 mpg UK respectively. Real-world figures are often even better with gentle driving, making it ideal for city and highway use.
Yes. Like virtually all modern DOHC engines, the P13B is an interference design. If the timing chain were to fail (which is extremely rare), the pistons would collide with the valves, causing catastrophic engine damage. The timing chain is designed to last the life of the engine with no scheduled replacement.
Honda recommends 0W-20 synthetic oil for optimal fuel economy and VTEC operation. 5W-30 is also approved, particularly in hotter climates. Change intervals should not exceed 10,000 km or 12 months. Using the correct viscosity is especially important for pre-2012 models to manage oil consumption.
