Peugeot 207 B2699 Engine Trouble Code
What is Peugeot 207 B2699?
The Peugeot 207 B2699 check-engine light can indicate issues ranging from minor (loose gas cap) to serious (catalytic converter failure). Professional diagnostic scanning at a dealer or shop will identify the exact cause and required repairs.
B2699 on the Peugeot 207
The Peugeot 207 features a sequential multi-port fuel injection (SMFI) system where injector timing is tightly synchronised with the crankshaft signal. Wear on the crankshaft reluctor ring teeth produces signal dropout events that accumulate and eventually trigger B2699.

How to Fix Peugeot 207 B2699
Diagnostic Steps:
Check if fuel pump primes when key is turned to ON. Measure fuel pressure and verify bright white-blue spark at all plugs. Also verify mechanical timing alignment.
Repair Solution:
A/C pressure sensor monitors refrigerant pressure changes. DTC sets when pressure change falls outside calibration. Verify A/C system function, refrigerant charge, and electrical connections.
Technical Notes:
For B2699, verify VCT solenoid operation. Look for stuck or sticking valves caused by contamination. Consult vehicle-specific repair manual for proper component testing procedures.
Peugeot 207 B2699 Repair Cost
Ground circuit repairs on the Peugeot 207 — a common cause of B2699 — are labour-intensive but parts are cheap. Expect 1.5–2.5 hours of labour ($120–$200) to clean, treat, and re-torque all engine and transmission ground straps. This is excellent value given how often it resolves persistent fault codes.
B2699 Description
B2699 engine trouble code is related to Reverse Input Circuit.
Main Cause
The primary reason for B2699 OBD-II Engine Trouble Code is: Fuel Temperature Sensor B Circuit Range/Performance.
Common B2699 Misdiagnosis on the Peugeot 207
When Peugeot 207 presents B2699 with a concurrent coolant temperature DTC, technicians sometimes replace the thermostat rather than the coolant temperature sensor (CTS). The CTS is a $15–$25 component; the thermostat job carries 1–2 hours of additional labour.
DIY Repair Guide: B2699 on Peugeot 207
When replacing sensors on the Peugeot 207, always use anti-seize compound on the thread and dielectric grease on the electrical connector. This simple habit prevents the most common causes of sensor-related callbacks after repair.
Preventing B2699 on the Peugeot 207
For diesel Peugeot 207 owners, a DPF (Diesel Particulate Filter) regeneration run on the motorway every 500 miles prevents soot blockage that back-pressures the exhaust and forces B2699 flags via the pressure differential sensors.
Frequently Asked Questions — Peugeot 207 B2699
A: Yes. A weak battery causes voltage drop during cranking that confuses the ECU and can store a range of fault codes. Always rule out battery and charging system health before diagnosing sensor-related codes.
