Given the robust nature of today's emissions control components, it is entirely possible for an individual component to malfunction without leading to an immediate increase in emissions at the tailpipe. The OBD system looks for broken or malfunctioning emissions control components while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits.
FORD ENGINE CODES P20B9PS AND P008A CODE
OBD 2 P008A Land Rover code and tailpipe testing are two different approaches to identify vehicles in need of repair. P008A Land Rover Description For All Models : Other manufacturers sometimes use an alternating pattern in the V-engines. In the V-6 configuration, cylinder 4 is at the front right of the engine and in a V-8, cylinder number 5 is in that location. In the V-engine design, Ford follows a similar design with the number one cylinder at the front left of the engine. In-line Ford engines, along with those of most other manufacturers, begin the numbering of cylinders at the front and proceed in numerical order toward the back. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.Īccelerator Pedal Position Sensor 1 Circuit Low and P2127 - Accelerator Pedal Position Sensor 2 Circuit Low would lead you to suspect a defective accelerator pedal position sensor. P008A Land Rover OBD2 reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem.
