P0014

P0014 B Camshaft Position Timing Over-Advanced (Bank 1)

P0014 indicates b camshaft position timing over-advanced (bank 1). The exact repair depends on whether the underlying issue is a sensor fault, wiring problem, mechanical wear, or a related system problem on the vehicle being diagnosed.

How to use this page

This page explains the code in plain English and gives indicative UK repair and MOT context. It does not confirm the exact failed part. Vehicle age, engine, related codes, live data, and workshop inspection can all change the final diagnosis and quote.

What does fault code P0014 mean?

P0014: Bank 1 exhaust cam timing too advanced, causes rough running. Check oil level and VVT solenoid first (£50-£500). When this fault is detected, the ECU (Engine Control Unit) stores the code and usually illuminates the check engine light on the dashboard.

In practice, P0014 should be treated as a timing, position and ignition control problem first, not as proof that one named part has failed. The value of the code is in narrowing the system, checking related data, and avoiding the usual misdiagnosis before parts are ordered.

Symptoms of fault code P0014

These are the most common symptoms UK drivers report when this code is active:

  • Check engine light on
  • Rough idle
  • Hesitation on acceleration
  • Engine may run poorly at low RPM
  • Poor fuel economy

Note that some vehicles show no drivability symptoms at all — the check engine light may be the only sign. This is why scanning the fault code is essential rather than guessing at the cause.

What causes P0014?

These are typical causes to check first:

  1. Exhaust camshaft timing over-advanced
  2. VVT solenoid fault on exhaust cam
  3. Oil flow issue affecting exhaust camshaft phaser
  4. Timing chain stretched
  5. Dirty oil clogging exhaust VVT galleries

It is important to diagnose the root cause before replacing parts. Many unnecessary and expensive repairs happen because the most expensive component is replaced first without proper testing. Always work through the diagnostic steps systematically.

How to fix P0014 — step by step

Work through these steps in order to avoid unnecessary parts replacement:

  1. Check engine oil level and condition — dirty oil affects VVT timing
  2. Test exhaust VVT solenoid operation with live data
  3. Check exhaust camshaft timing — compare actual vs commanded
  4. Inspect timing chain if oil and solenoid tests are normal

After any repair, clear the fault code with an OBD-II scanner and carry out a test drive. If the code returns, continue to the next diagnostic step. For a personalised repair guide specific to your vehicle's make, model, year and engine, use our AI Diagnostic Report below.

UK vehicles commonly affected by P0014

These models are frequently seen with this fault code in UK garages:

  • Ford Focus/Mondeo (1.6/2.0)
  • Vauxhall Astra/Vectra (1.8/2.0)
  • Volkswagen Golf/Passat (1.8/2.0 TSI)
  • BMW 3/5 Series

This code can appear on OBD-II compatible vehicles. OBD-II is standard on most UK petrol cars from 2001 and diesel cars from 2004, with many later-1990s vehicles also compatible. The models listed above are examples where owners and garages often encounter this fault, but they are not an exhaustive or ranked list.

DIY difficulty and cost guide

Difficulty: Medium — solenoid replacement is DIY. Timing chain work needs a professional.

UK repair cost estimate: £50–£500 including parts and labour at average UK workshop rates (inc. VAT). Independent garages are typically 30–50% cheaper than main dealers. Always get at least two quotes.

Prevention: Change engine oil every 10,000 miles, use correct oil spec, fix oil leaks promptly.

Detailed analysis for P0014

What usually triggers P0014 on UK cars

P0014 sits in the engine-position, timing, or ignition-control family. These faults often overlap with wiring issues, sensor plausibility, ignition breakdown, and on some engines genuine timing drift or chain wear.

Checks that save money before replacing parts

  1. Check signal quality and wiring before ordering sensors.
  2. If the engine has timing-chain or VVT history, compare synchronization data before replacing parts.
  3. For ignition-specific faults, isolate the affected coil or circuit before assuming deeper engine damage.

Common misdiagnosis to avoid

The common error with P0014 is replacing the named sensor or coil too early. These faults need you to prove whether the problem is electrical, signal-related, or mechanical timing-related.

Questions to ask your garage about P0014

  • Was signal or synchronization data checked live?
  • What electrical tests proved the circuit is good or bad?
  • Could timing drift or VVT behavior explain the code?

P0014 and the UK MOT test

Fault code P0014 does not directly cause an MOT failure on its own, but it can still cause a failure if it keeps the check engine light (MIL) on where MIL inspection applies, or affects emissions.

Even if the light is not currently on, if the fault is intermittent it could reappear during the test. Use our AI Diagnostic Report to understand the MOT risk specific to your vehicle and get advice on whether it is safe to proceed to your test.

Frequently asked questions about P0014

What does P0014 mean in plain English?

P0014 is a timing, position and ignition control fault code. In practice, P0014 should be treated as a timing, position and ignition control problem first, not as proof that one named part has failed. The code helps narrow the system, check related data, and avoid misdiagnosis before parts are ordered.

Will P0014 fail an MOT?

P0014 does not automatically fail an MOT on its own, but the underlying fault can still cause a failure if it affects safety, warning lights, or emissions.

Can I keep driving with P0014?

Driveable but fix promptly — often caused by a worn timing chain or low oil pressure.

How much does it usually cost to fix P0014 in the UK?

Typical UK repair costs for P0014 range from £50–£500, depending on the underlying fault, your exact vehicle, and local labour rates.
