Computer Codes OBDII

[mark v]

Please no code help posts here, this is only for your reference. If you need code help please start a new topic.

The codes are not all in order, however I feel like I posted them all except I dont have any ABS codes.

P0100-P0199 - Fuel and Air Metering
P0200-P0299 - Fuel and Air Metering, Injector Circuit
P0300-P0399 - Ignition System or Misfire
P0400-P0499 - Auxiliary Emissions Controls
P0500-P0599 - Speed Controls and Idle Control System
P0600-P0699 - Computer Output Circuit
P0700-P0799 - Transmission
P0800-P0899 - Additional Transmission
P1000-P1999 - Codes Specific to Ford vehicles

A Ford P0171 is a LEAN code fpr cylinder bank 1, and P0174 is a LEAN code for cylinder bank 2. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel).

When the Check Engine Light comes on, either one of these codes, or both, may be found when a code reader or scan tool is plugged into the vehicle diagnostic connector. IF the vehicle is driven long enough, typically both codes will be set.

A P0171 lean code for bank 1 is the cylinder bank on the RIGHT (passenger) side of the engine on Ford vehicles with a V6 or V8 engine and rear-wheel drive.

A P0174 lean code for bank 2 is the cylinder bank on the LEFT (driver) side of the engine on Ford vehicles with a transverse-mounted V6 engine and front-wheel drive. This code is not set on four cylinder engines (no bank 2).
