Dodge Custom B2699 Engine Trouble Code
What is Dodge Custom B2699?
Dodge Custom B2699 code can indicate a faulty oxygen sensor, which may eventually damage the catalytic converter (repair cost: $2,000–$2,200). Professional diagnosis costs around $200–$210. Oxygen sensors are often straightforward to replace — check your owner's manual for location and instructions. This issue should be addressed promptly to prevent further damage.
B2699 on the Dodge Custom
Dodge Custom models produced in the mid-cycle refresh years show a statistical uptick in B2699 occurrences linked to the variable valve timing (VVT) actuator. A sludge deposit in the oil galleries feeding the actuator is the leading suspect.

How to Fix Dodge Custom B2699
Diagnostic Steps:
Regarding B2699, carefully inspect the wire harness near the intake manifold bracket, best accessed from below near the oil filter. Look for chafing, pinching, or damaged insulation.
Repair Solution:
Excessive air inflow may result from vacuum leaks, dirty sensors, or EGR valves not closing properly. Insufficient fuel can stem from dirty injectors, clogged filters, weak fuel pump, or leaking pressure regulator.
Technical Notes:
B2699 DTCs can be triggered by upstream issues. For example, a dirty MAF sensor may cause incorrect fuel-trim adjustments, leading oxygen sensors to report mixture problems. Address root causes first.
Dodge Custom B2699 Repair Cost
A Dodge Custom B2699 fault caused by ignition coil failure costs roughly $90–$160 per coil including labour. Replacing all coils simultaneously — rather than one at a time — is recommended because coils typically age at similar rates. This preventive approach keeps total cost below $500.
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 Dodge Custom
Replacing the PCM/ECU on the Dodge Custom for a persistent B2699 is a last-resort action that is often performed prematurely. Statistically, less than 2% of B2699 faults on this platform originate in the ECU; wiring, sensors, and mechanical causes account for the remainder.
DIY Repair Guide: B2699 on Dodge Custom
The fuel pressure test on the Dodge Custom requires a Schrader-valve type fuel pressure gauge ($25–$40) connected to the fuel rail test port. With the ignition ON (engine off), pressure should hold above 30 PSI for two minutes. A rapid drop confirms a leaking injector or failing regulator as the root cause of B2699.
Preventing B2699 on the Dodge Custom
Verify that the Dodge Custom engine air box lid clips are fully seated after any air filter service. An unsealed air box is a direct path for unmetered air past the MAF sensor and is an extremely common — and extremely embarrassing — cause of B2699.
Frequently Asked Questions — Dodge Custom B2699
A: Yes. Some fault conditions, particularly those involving EVAP system leaks or marginal sensor readings, store codes without producing noticeable drivability symptoms. These are called memory faults and still need to be addressed because they will eventually cause performance issues.
