Clean the mass air flow sensor inside with a non-chlronated brake cleaner and replace the air filter then clear the codes in the computer and see if they come back.

SOURCE: codes p2106

I think you'll find it's a problem with your throttle you might need to talk to you local ford dealer but don't get talked into getting bit's replaced! I've been tld that you can put a recommended cleaner into your fuel tank and this can sometimes cure the problem - worth a go................

SOURCE: i have a 2004 ford

this could be your switch problem, or a relay problem. you need to link out the supply yo the side lights from your switch, if they work it is your switch gone. if they do not work you need to look in your handbook to see where the sidelight relay is and do the same there link it out direct if the lights work your relay is faulty and needs replacing. hope this helps.

I had the same problem. Turns out,( and I didn't believe it when I was told) but, my problem turned out to be cheap (inferiour) plugs and wired. I was reccomended to use NKG plugs and Borg-Warner wires.

SOURCE: 2004 sebring 2.4 x engine running rough

The code description for Diagnostic Trouble Code (DTC) P0138 is "Oxygen Sensor Bank 1 Sensor 2 shorted to voltage" The oxygen sensor (O2S) voltage should always be between 0 and 1 volt. This code sets when the O2S voltage is greater than 1.2 volts for at least 30 seconds.

The code description for code P0117 is "Engine Coolant Temperature Sensor (ECT)Voltage Low". The ECT is a thermal variable resistor. The Powertrain Control Module (PCM) sends a 5 volt reference to the ECT and measures how much of this voltage returns to the PCM to determine engine temperature. This code sets when the ECT voltage signal is less than 1 volt.

Here's the kicker...which came first, P0117 or P0138? Low ECT voltage can cause the engine to run extremely rich and cause the O2S voltage to go high. This needs to be looked at with a scanner that can display the actual ECT and O2S voltages so they can be compared.

I would say that with the symptoms you are describing along with these codes, there is a GOOD chance that you have some kind of wiring harness damage or water in a connector that is shorting these two circuits together. This would definitely RAISE the voltage on the O2S circuit that is supposed to be low, and LOWER the ECT voltage that is supposed to be high.

Start and dies, codes p061f, p2106,p2104,p2111

code p2106 refers to throttle actuator control (TAC) system--limited power mode===causes ---wiring---TAC motor---APP sensor---ECM

code o2104 refers to TAQC systems ---forced idle mode===causes wiring---TAC motor--APP sensor--ECM

code p2111 refers to TAC system --actuator stuck open ==causes ---throttle body--throttle valve tight/ sticking

code p2111 also refers to TAC system --circuit malfunction==causes wiring---short to positive--short to ground---TP sensor---ECM

code p2111 also has a 3rd section---brake vacuum---implausible signal===causes---wiring---vacuum sensor--mechanical fault

Make a very long technical story short,
because I have the same car

You have 1 really bad COP Ignition Coil

You should have PO301 thru PO 308 Codes
as well as a lot of others

The tool light comes on after traveling

The dealer should be able to read the trouble code.

This can occur with the TCM (Transmission Control Module) and/or ECU program. This may require either a re-flash or a program download to the ECU. The ECU program is not a warranty item, but is typically in the $75 to $100 range.

However there is a Technical Service Bulletin (TSB) for the “wrench light”.

TSB 05-14-4

This article supersedes TSB 05-09-15 to update the Issue and Dealer Coding.

2003-2005 Thunderbird
2005 Crown Victoria, Mustang
2004-2005 Explorer, F-150
2005 E-Series, Expedition, F-Super Duty
2003-2005 LS
005 Town Car, Navigator
2005 Grand Marquis
2004-2005 Mountaineer

Some vehicles built 11/29/2004 and prior may exhibit the wrench light on with both P2106 and P2135 diagnostic trouble codes (DTCs).

Replace the throttle position sensor (TPS) following the instruction sheet included in the TPS service kit. Reprogram the powertrain control module (PCM) to the latest calibration using WDS release B36.11 and higher, or B37.2 and higher. This new calibration is not included in the B37 CD. Calibration files are also available at

I hope this helps!

P2106 on 2004 f150

The throttle position sensor (TPS) is bad, you'll need to replace it in order to correct his code. The part should run you about $40 or so.

There is a tech bulletin from ford on this code.You did the correct repair, but also the pcm has to be reprogrammed from the dealer ,which is also known as flashing the pcm:)
