Acura MDX MAP Sensor Replacement Guide
How to clean or alter a faulty manifold absolute pressure sensor in a 1st generation 2001 to 2006 Acura MDX.

2006 MDX iii.5L V6 Engine
Pry Off Bolt Cover
Left Rear Bolt Cover This automotive maintenance tutorial was specifically created to assist owners of the offset generation (2001, 2002, 2003, 2004, 2005 & 2006) Acura MDX in cleaning or changing the MAP (manifold absolute pressure) sensor in the throttle torso of the VTEC 3.5 liter V6 engine.

Owners of other Acura or Honda vehicles such as the RDX, ILX, TLX, RLX, TL, CL, RSX, RL, TSX, ZDX, NSX, Integra, Pilot, Accordance, Civic, Fit, Clarity, CR-V, CR-Z, 60 minutes-Five, Odyssey, Element and Ridgeline may also discover these DIY instructions to be helpful.

The OEM MAP sensor was the Denso 079800-5410.

Other uniform replacement MAP sensors with their role numbers are as follows: Standard Motor Products AS191, Wells SU5585, Airtex 5S2404 and Spectra MP118.

The tools needed to access and replace the MAP sensor include a pocket-sized flathead screwdriver, a 10mm socket with a ane/4" drive ratchet and a Phillips caput screwdriver.

Some of the possible symptoms of a faulty MAP sensor include a rough idle, loss of ability, lower fuel economic system (MPG), a failed emission (smog) test, stalling, fouled spark plugs, detonation (knocking / pinging), hesitation and/or surging.

The engine error codes (A.K.A. check engine lite "CEL", service engine shortly "SES" or problem codes) that indicate a trouble with the MAP sensor are as follows: P0108 Loftier Voltage, P0107 Low Voltage and P0106 Range / Performance.

Front end Right Bolt Cover
Rear Right Bolt Cover
Loosen Counterclockwise The showtime step is to open the hood to access the engine bay.

So locate the small round black plastic bolt covers on the top of the plastic engine cover.

There are four bolts that concur the plastic engine cover in place.

The ii plastic covers in the middle of the engine embrace at the front and rear are decorative and do non need to be removed.

Remove the four plastic bolt covers at the front left, rear left, forepart right and rear right of the engine cover.

Use a modest flathead screwdriver to gently pry up the bolt covers.

To prevent from scratching the plastic surfaces, you may cull to either cover the tip of your screwdriver with a thin micro fiber cloth or instead apply a plastic pry bar tool.

Remove Front Left Bolt
Remove Front Right Commodities
Remove Right Rear Bolt Set the four plastic bolt covers bated in a prophylactic place.

Remove the four bolts on the top of the engine cover by turning them counterclockwise with a 10mm socket, a curt extension bar and a 1/4" drive ratchet.

Covers & Bolts Removed
Plastic Engine Cover
Engine Cover Removed Set up the four bolts aside in a safe place.

Advisedly lift the plastic encompass off the superlative of the engine.

Ready the engine comprehend aside in a safe place.

Pinnacle of Throttle Trunk
Push In Release Tab
Pull Off Electric Connector Move to the right (driver) side of the engine bay.

Locate the circular blackness prophylactic air intake hose that leads into the foursquare shaped silverish metal throttle body.

The small black plastic manifold absolute pressure level sensor is situated at the top of the throttle body.

The original MAP sensor on my 2006 MDX had a bluish and silver sticker label.

The OEM sensor in my SUV was part number Denso 079800-5410 5V PS-4A 8G31 and was made in Nippon.

Push in the release tab on the electrical connector earlier pulling the power plug directly off the former MAP sensor.

Phillips Head Spiral
Loosen Counterclockwise
Single Bolt Removed Remove the single bolt that secures the MAP sensor to the throttle body past turning it counterclockwise with either a Phillips head screwdriver or a flathead screwdriver.

Set the commodities aside in a safe place.

Rotate Old MAP Sensor
Pull Out Former MAP Sensor
Inspect Old MAP Sensor Carefully pull the old MAP sensor out of its port on the top of the throttle torso.

If you lot have trouble removing the old sensor, try gently rotating it back and forth while pulling up.

Inspect the quondam MAP sensor for any oil, soot, sludge or other debris. Check to make sure the rubber o-ring gasket is not damaged.

Audit Rubber O-Ring
MAP Sensor Port (Pigsty)
Line Upwardly New MAP Sensor Since the MAP sensor does non really sit in the air menstruum, it should not be very dirty.

You'll find that the port for the MAP sensor is generally enclosed with a curved metallic bottom at the lesser of the well.

There is simply a pocket-sized hole on the left (passenger) side of the port virtually the "27" stamped on the height of my throttle body in the pic above.

My MAP sensor is over 11 years erstwhile and however looks brand new.

If you would like to endeavour cleaning the quondam MAP sensor to run across if that solves your engine problems, I recommend that you use some CRC Electronic Cleaner which dries without leaving whatsoever remainder on electrical parts.

Spray the electronic cleaner into the MAP sensor itself and also the electrical connector. Permit both of them to fully dry out.

If yous already have some MAF cleaner on hand, that would besides work.

Continue in mind that a MAF (mass air catamenia sensor) is a heated wire that actually sits in the air flow stream within the throttle trunk or air intake tube. So information technology is much more probable to collect soot, oil or debris.

And so if your Acura or Honda has one of the MAP error codes (P0108, P0107, P0106), the old MAP sensor almost likely needs to be replaced.

(The engine mistake codes are defined as follows: P0106 - MAP Barometric Pressure Circuit Range/Functioning Problem, P0107 - Manifold Absolute Pressure Barometric Pressure Circuit Low Voltage Input and P0108 - MAP Barometric Pressure Circuit Loftier Voltage Input.)

Push In New MAP Sensor
Re-Insert Screw
Tighten Clockwise If you buy a new MAP sensor, I recommend buying the Standard Motor Products AS191 since it has fantabulous review on Amazon.

Some people like to apply a small amount of silicon grease or new motor oil to the rubber o-ring gasket on the new MAP sensor.

Line up the new sensor with the port on the throttle body.

Gently button the new MAP sensor direct downwards into identify.

Try to avoid twisting or rotating the new sensor to prevent form damaging the prophylactic o-ring.

Re-insert the bolt and tighten information technology in the clockwise management with the Phillips head screwdriver until it is snug.

Avoid over tightening the commodities to forestall from cracking the plastic sensor housing.

Push On Power Plug
Electrical Connector Secured
Supplant Engine Encompass Push the electrical connector direct on to the new sensor.

The plug should "click" securely into identify.

You lot may want to start the engine and check to see if the new MAP sensor has cleared upward your error codes.

If necessary, utilise an OBD II (A.K.A. OBDII or OBD2) scanner to clear the error codes, or you tin can endeavor disconnecting the 12V automotive battery for at least 15 minutes.

Lower the plastic engine encompass back into place.

Line Up Bolt Holes
Lower In Bolts
Spin In Clockwise Line upwardly the bolt holes in the plastic comprehend with the holes on the top of the motor.

Spin in the four bolts a few turns by hand in the clockwise direction to prevent them from becoming cross threaded.

Tighten Clockwise
Button On Commodities Covers Tighten the four bolts by turning them clockwise with the 10mm socket, an extension bar and a 1/4" drive ratchet until they are snug.

Avoid over tightening the bolts to prevent from groovy the plastic engine encompass.

Gently pop the round plastic bolt covers dorsum into place.

Be sure to tape the MAP sensor change in your SUV's service records.
