The "Anti-Lock" and "Disable" messages appearing while driving your 2004 Pontiac Aztek, along with the limitation of the accelerator not going past 2000 RPMs, suggest that there might be an issue with the vehicle's electronic systems or sensors. This could be related to the vehicle's traction control system, engine management system, or other interconnected systems. Here are a few potential causes:
Wheel Speed Sensors: The Anti-Lock Brake System (ABS) relies on wheel speed sensors to detect the speed of each wheel. If one of these sensors is malfunctioning or sending incorrect signals, it could trigger the ABS warning and potentially affect other systems.
Traction Control System: The traction control system works in conjunction with the ABS to help maintain traction during acceleration. If there's a problem with the traction control system, it could lead to the symptoms you're experiencing.
Engine Management Issues: The limitation of the accelerator not going past 2000 RPMs could be related to the engine control module (ECM) detecting a fault in the vehicle's systems and entering a "limp mode" to protect the engine. This could be triggered by various issues such as a faulty sensor, air intake problems, or more.
Wiring or Connector Problems: Electrical connections and wiring harnesses play a crucial role in the communication between different systems in the vehicle. Damaged or corroded wires, connectors, or fuses could lead to erratic behavior.
Faulty Sensors: Various sensors throughout the vehicle, including those for the throttle position, oxygen sensors, and more, play a role in determining engine performance. A faulty sensor could cause the engine to go into a restricted mode.
Software or Computer Issues: Modern vehicles rely heavily on electronic control units (ECUs) and software. If there's a software glitch or issue with the vehicle's computer systems, it could lead to unexpected behavior.
