I put new intake manifold sensor on car as old one was faulty. Problem is warning light is still showing

did you erase code with diagnostics after doing job. Maybe that's why.

Check out this website: http://engine-codes.com/p0108_chrysler.html
'P0108 - Manifold Absolute Pressure/Barometric Pressure Circuit High Input (possible Map Sensor)
Possible Causes:
Faulty Manifold Absolute Pressure sensor
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
Possible Symptoms:
Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation"

Do you mean p0107 ? If so that is P0107 Ford - Manifold Absolute Pressure/Barometric Pressure Sensor Low Input

Possible causes
- Faulty Manifold Absolute Pressure sensor
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM) What does this mean?
When is the code detected?
The ECM has detected a performance fault with the MAP sensor
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 Ford Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.

P0152 P0152 - O2 Sensor Circuit High Voltage Bank 2 Sensor 1Possible causes - Faulty Front Heated Oxygen Sensor Bank 2
- Intake air leaks may be faulty
- Exhaust gas leaks
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
eplacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust P0152 Description The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

The website has software that looks for obscene words.
I would think a compression test would show if the cylinder is having mechanical problems. And yes the intake or head gasket could be leaking again, especially if the intake or head were warped or cracked.
Have you checked fuel pressure ?
Does the spark plug for cylinder 5 show signs of coolant leaking into the cylinder ?

An intake manifold leak could cause this, or a vacuum leak somewhere. Spray carb cleaner around the intake mounting. If you notice a difference in idle, the intake manifold gasket may be leaking. Idle control valve may be faulty? MAF sensor needs cleaning? Use a sensor-safe cleaner for that. Were any sensors or controls different on the two engines? Use the ones from your old engine, if any differences exist. Good luck.

.P1031 Intake manifold air control valve position sensor
Possible Causes - Intake manifold air control valve position sensor circuit open circuit
- Intake manifold air control valve position sensor circuit poor electrical connection
- Faulty intake manifold air control valve position sensor
- Intake manifold air control flap too tight or sticking a four thumbs up rateing will be appreciated thank you have a nice day

Knock sensor replacement requires the removal of the intake manifold as the knock sensors are under it.

i had the same code, p2187. check to the left of the throttle body(side facing the front of the veh.
there are 2 vaccum hoses going into the intake. the larger one on top has a spring clip holding it and if you look under that you'll see a smaller one with a check valve. mine was disconnected. plugs in under the larger one.
