Had a code with message service engine now. Engine failure or something. Towed car home. Had air filter replaced and coolant filled and drives like nothing happened? Should I still worry?

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.

P0106
Descriptor
Probable Causes
Manifold Absolute Pressure (MAP) Sensor Malfunction
Manifold Absolute Pressure (MAP) Sensor Responding Slowly
Mass Air Flow (MAF) Sensor Malfunction

DM: Manifold Pressure Sensors

DM: Introduction See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > DM: Manifold Pressure Sensors - Introduction

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
.

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.

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

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.

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?

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.

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

Again, how many miles on the car?

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.

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.
