What actually causes P1340 on a Ford
Ti-VCT engines log P1340 when the intake variable-valve solenoid sticks open with oil sludge — symptom is rough idle and reduced economy. Oil and filter on schedule is the prevention.
Ford engines that log P1340
- 1.6 Ti-VCT Sigma (Fiesta/Focus)
- 2.0 Duratec HE
- 1.6 EcoBoost
How we diagnose P1340 on a Ford
- Inspect oil condition / service history
- Activate VVT solenoid via FORScan output test
- Replace VVT solenoid and fresh oil/filter
- Re-test live cam timing under rev
The common misdiagnosis to avoid
Don't replace the cam sensor first — on Ti-VCT it's almost always the VVT solenoid (£55) sticking due to dirty oil.
Ford P1340 repair cost in the UK
Expect £90–£380 including parts and labour at an independent garage. Main-dealer quotes on Ford are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
