Coode P0106

Good morning,

I attached some possibilities below for the failure.

You need to have it addressed. It will not go away until the issue is diagnosed, repairs made and clarification are confirmed.

The mass air flow sensor, connector and voltages all need to be checked.

DM1 CHECK FOR DTCS


Note:This pinpoint test is designed to diagnose multiple components in the same test steps, only measure the circuits that apply to the vehicle and the component being diagnosed.
Note:Diagnose circuit concerns before range or performance concerns.
Are DTCs P0106, P0107, P0108, P0109, P012B, P012C, P012D, P012E, P0236, P0237, P0238, or P025E present?
Yes

- GO to DM2
.

No

- For symptoms without DTCs, GO to DM2
.

- For all others, RETURN to Section 3 See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > SECTION 3: Symptom Charts
, Symptom Charts for further direction.



DM2 MONITOR THE MAP PID


- Ignition ON, engine OFF.

- For the TCIPT sensor.

- Access the PCM and monitor the TURBO_INLET_V (VOLT) PID.

- For the TCBP or TCBP/CACT sensor,

- Access the PCM and monitor the TCBP_V (VOLT) PID.

- For all others,

- Access the PCM and monitor the MAP_V (VOLT) PID.
Is the voltage between 0.05 - 4.95 V?
Yes

- For DTCs P0106, P012B or P0236, GO to DM9
.

- For all others, GO to DM8
.

No

- GO to DM3
.



DM3 CHECK THE VOLTAGE BETWEEN THE VREF AND SIGRTN CIRCUITS

But car been driving great with no issues now. brother thinks cause we had a weird storm that evening. warm then a downpour?

But car been driving great with no issues now.

Yes, I understand but the issue will return.

Better to be proactive and have it checked and not have it fail on the road and cost you time and more inconvenience.

Unfortunately, cars cannot fix themselves. The check engine light is a call for help.

Roy

Can a dirty air filter and very low coolant/water cause a P0106?

No, it cannot.

Roy

Almost two weeks ago after a storm my car message service engine now came up and was stuttering at gas pedal. Towed home. Code P0160 came up. I noticed there was almost no coolant and air filter was dirty. Replaced both. Been driving great since. should I worry? Could lack of coolant somehow be the problem or dirty air filter?

Good afternoon,

Can you verify the code number? There is no code 160.

Roy

Hello,

I am not finding Direct Trouble Code (DTC) P0160 for your vehicle. Could you please double check the DTC and get back to us with what you find out?

Thanks,
Alex

Yes a code P0106 came up on my 2015 Ford Escape which I know is some sort of sensor 2. But after coolant and new air filter drives great.

Okay, we both do not find this code listed.

Where did you get this code? Did you use a reader or did someone tell you the code?

Roy

Oops, P0106.

That makes a big difference.

Okay, if you have less than 50,000 on your car, this is all warranty. You have a 5 year 50,000 warranty on check engine lights.

The mass air flow sensor has a fault. I posted a flow chart, picture and the part for you to view.

Thanks guys I appreciate it. Didn't know if I should worry as it has been driving great and has coolant and new air filter?

The code indicates a fault. I would not ignore it at all.

Again, how many miles on the car?

Roy

Thanks guys I appreciate it. Didn't know if I should worry as its been driving great and has coolant and new air filter???

75,000 but car runs great. The night code came up was a storm. went from hot to downpour. Atmospheric? Could it be possible and there was almost no coolant?

Okay, no warranty.

No to the coolant. It will not cause the issue.

Water may have got in the sensor and caused the code. I would drive it and see if it comes back. If it does, it needs to be checked. If not, then you are good to go.

Roy

That is what I thought. Has a new hood and it was a big storm. Should I try and keep water from getting in engine? I have been afraid to take it through a car wash.

Car washes are okay. I would not worried about that at all.

Roy

But can water get in again? Thank you for your time. :)

Heavy rains and downpours, yes it can.

You're welcome

Always glad to help.

Roy

Roy...how would I prevent from happening again? Thanks again

You cannot. You just need to be careful about driving in heavy rain. When it gets intense, pull over somewhere safe.

Roy

It was parked in a lot. Do I need to worry every time there is a downpour?

No, not at all. Just be careful in the rainstorms that bring heavy rain.

Roy

Has your vehicle been to the dealer for any recalls? Specifically the recall for the engine wire harness splice repair? I have repaired several of these vehicles for faulty wire repairs when the recall was performed. What happens is the tech has to cut open the wire loom and tape to access the splices to repair them, some techs do this with a razor blade and inadvertently cut through several other wires exposing the bare wire to the elements. When the vehicle’s wiring gets wet, strange things happen to say the least. This is just one possibility that I’ve personally seen happen. The harness in question is at the front of the engine between the radiator and the engine.

Thank you..I wondered about it getting water inside map sensor or something... Wires getting wet can cause a map sensor code? Strange thing last night though it wasnt raining and went to store and parked...key was in ignition and turned engine on again and message came up"engine failure..service engine now...but this time I turned engine off and restarted and car ran great...no problems at all. ???

Is the light still on? If it is, have the code rechecked again. A parts store will pull it for free.

Roy

No message at all. It flashed on then when I turned car off then on again it was just fine and ran fine.

Something is going on.

You will need to wait until it is more consistent. Then when the light stays on, get it checked and get back to me.

Roy

Hopefully it won't since it drives good. When message came on that first night I couldn't drive it atall and there was some clear steam which thought it was from previous heavy downpour

Okay, I am afraid and sure it will come back.

Keep us updated if you have any other questions.

Roy

The recall for the wire repair was for the signal return splices and the most common failure was related to the map signal circuit. You can contact your local Ford dealer and give them your VIN# so they can look your vehicle up to see if the recall is available for your vehicle. If it is, absolutely do it!

Question, my vehicle first week I bought said 24.2 miles per gallon, brother put new brakes rotors etc and new air filter in. I drive pretty much same roads etc. now says 21.2? Normal?

Good morning,

By the site rules, we deal with one issue at a time.

Please start a new question and we will be glad to help you with that concern.

Roy

Okay, so I was going home from work and stopped at store. When I got to my car to go home..it happened again. "Engine failure... lService Now"..and was really rough and I turned car off and waited like 30 seconds to a minute. Started car and no messages and no problems, car drove fine. I appreciate all your guys help. My brother is out of town and single parent and I have anxiety and I don't know how to do things with engine. Should I just replace map sensor?. Thanks so much again for taking the time for me.

Good morning,

I would go to a parts store and have them read the code that is stored. Get back to me with the code.

Roy

Engine light was on for first time tonight. O'Reillys said it was only code 0456 that came up. And he said cause I don't have a gas cap and air and water can get in there here in northwest. The PO106 didn't show up with the engine failure/service engine now from last night. Exact same symptoms as a few weeks ago when my brother came up with P0106? He also checked voltages tonight. Everything came up good. Said battery was good but needed charging...not sure if something might be loose in back as why its not getting charge from alternator etc? I called Ford dealership and she said my VIN doesn't tell her anything except if work had been done there. No recalls she said. And also NTHS said no recalls. What you think?
Thanks again

What was the charging voltage?

The 456 is an evap code. That code will not affect the running of the car at all.

What was the charging voltage?

Roy
