B2737 Ford Concept Diagnostic Trouble Code
B2737 Ford Concept code definition:
B2737 is a kind of OBD-II Diagnostic B-Body Diagnostic Trouble Code for Ford Concept.
B2737 Ford Concept is described as Fuel Rail Pressure Sensor Circuit Malfunction. This code is strictly about the incoming signal from the FRP (fuel rail pressure) sensor falling below the calibrated limit for a certain period of time. As you drive and when specific conditions are slowly met, the vapors will gradually purge from the charcoal canister and will get burned within your engine.
Symptoms
Symptoms of a B2737 Ford Concept diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
- Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- IC Circuit High Voltage Problem
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- PCM Stack Overrun Problem
Repair Processes :
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for.

Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before B2737 Ford Concept.
Fortunately, B2737 Ford Concept is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
