    Is it safe to continue driving it like this for another 7 days until I can get it fixed?

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!

What do these diagnostic codes(PO106,PO121) mean for a 2000 deawoo lanos.


OBD II Fault Code
  • OBD II P0106
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.
Symptoms
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0106 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
Common Misdiagnoses
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

Check Engine light stays on. No other symptoms. If I reset the computer by disconnecting the battery, the check engine light eventually comes back on and stays on. Sometimes this takes weeks... sometimes...


you should have scan done for fault codes
but you could inspect the throttle body for carbon deposits and clean as required first and see how it goes

I have a 201 e250 van the code p1518 comes up,the service engine light is on,what is p1518,it also shuts off when ever i am at a stop sign


Hello! A P1518 is a Intake Manifold Runner Stuck Open...It is a device that is held in place by three bolts and is located on the front of the intake manifold...There are two Actuator Rods...A 4 wire connector plugs into the top...Pin #1=Black (ground)...Pin #2=Dark Blue/Light Green...Pin #3=Red...Pin #4=Dark Blue/Yellow...

Check the connector for loose, frayed, contaminated, or open wires...However the Actuator is more than likely jammed with carbon...
