This code will not cause a no start. Does the engine turn over but not fire or what?

HOW TO RESOLVE OBD11 Code P1518 showing on a 3.0 DOHC 1999 Ford Taurus


P1518 - Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle.
  • IMRC monitor signal circuit shorted to PWR GND or SIG RTN
  • Damaged IMRC actuator
  • Damaged PCM
An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault

Ford F140 4.2 Do Engine codes P0305, P0306, and P1518 relate to each other


I am assuming you mean F150 truck.
The answer is maybe.
Code 305 and 306 are missfire codes for cylinders 5 and 6.
Code 1518 is for a problem with the intake manifold runner control which could cause the other two codes.

P1518 FORD Description The Intake Manifold Runner Control (IMRC) is monitored for failure during continuous or key ON engine OFF self-test.
Possible causes - Intake Manifold Runner Control (IMRC) harness is open or shorted
- Intake Manifold Runner Control (IMRC) circuit poor electrical connection
- Faulty Intake Manifold Runner Control (IMRC) actuator
- Faulty Engine Control Module (ECM)

Mil comes on with p2004/ check valve stuck open. Where is the check valve located


P2004 - Intake manifold runner control (IMRC) stuck open (bank 1)
Description - This DTC is set when the IMRC is commanded closed, but the IMRC monitor indicated open. This DTC replaces P1518 and P1537.

Probable causes - IMRC monitor signal circuit shorted to PWR GND or SIG RTN
- Damaged IMRC actuator or solenoid
- Blocked vacuum hoses

Diagnostic aids - Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed.

This control valve generally is located on the back of the intake.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Obd 2 code reads p 15 18. There is no code number to relate to the problem. Do you have the answer? [ check engine light on 1999 ford taurus]


code p1518= intake manifold runner control (IMRC) malfunction (stuck open)

the intake manifold has two runners per cylinder, feeding each of the cylinder heads
the IMRC assemblies are located between the intake manifold and two air passages for each cylinder.
one air passage is always open and the other passage switches from means of a valve plate.
below 3000 rpm, this valve plate is closed to improve low speed performance.
above 3000 rpm, this valve plate opens to improve high-speed exceleration.
the valve plates are opened and closed by the IMRC deactivation by the powertrain control module
(pcm) if your car or truck is not affected by the error code, the pcm may need to be reprogrammed
so that the error does not come up again. or you can connect an obd2 scanner and reset ever y time
it comes up. good luck!

you need to make sure that the control solenoid has vacuum and power and ground at the connector, or it will set that code. as long as you did not drop the plenum would should be fine, locate the control solenoid you should be fine

97 Ford Taurus 24val 3.0L 6cyl, P1518 IMRC open


There is a technical sevice bulletin for this exact issue. Go to the dealer and request they reprogram the pcm. You should not pay more than a half hour labor, they'll probably try to get a diagnosis fee out of you. Tell them no, just reprogram the pcm to latest calibration. If this doesn't fix it, then repost or pay to chat, but that should fix ya.
