The P1519 code in your 2023 Ford Ranger indicates a malfunction in the Intake Manifold Runner Control (IMRC) system on bank 2. This Ford-specific code signals the variable intake system isn't functioning correctly on the driver's side of the engine.
Understanding Bank 2 IMRC
On Ford V6 engines, bank 2 is typically the driver's side (left) bank. The IMRC system on this bank operates independently of bank 1, though both should work in coordination for optimal performance.
Common Causes of P1519
- IMRC actuator failure on bank 2
- Stuck or binding butterfly valves
- Carbon deposits on valves
- Wiring issues to bank 2 actuator
- Position sensor malfunction
- Mechanical linkage problems
Symptoms of IMRC Bank 2 Failure
- Check engine light on
- Reduced engine performance
- Power loss at specific RPM
- Decreased fuel economy
- Possible rough running
- Hesitation on acceleration
