TPMS Replacement-Repair

[trixie10]

I have a 2007 Explorer that for the past month has run rough for several seconds at start. Today the "wrench" warning light went on while driving, but off and stayed off after stopping for gas. Went on and styaed on again later after having set an hour. From reading other posts sounds like the TPS is most likely. Is this an easy change? Anything I need to know to watch out for? I will try to get codes checked at parts store, but at worst a $75 sensor is cheaper than the Ford diagnostic.
Thanks

Thanks. I wanted to make sure I didn't have to disconnect something first. Now can you tell me where the fuel filter is located and how to change it?

I think you should be posting in the 2006 - 2010 Ford Explorer forum; http://www.explorerforum.com/forums/forumdisplay.php?f=110

This is the 2011 - 2013 Ford Explorer Discussion thread.

BTW, if the TPMS alarm is due to a low battery situation in the sensor, the others may not be far behind. I don't know what the average life span of these batteries are.

I have never seen the wrench light come on for the TPMS system. The TPMS system has its own indicator light in the dash. I would put a reader on the car and see what the DTC is. I am thinking that it is your ABS system acting up.
Also, the fuel filter is in front of the gas tank behind a metal plate. Search around in the 06-10 explorer forum and you will find the necessary info.

Thanks for the help. We put a reader on at the auto parts store and got a code that the torque control valve is closed if that makes sense. Wrench light wsn't on at the time.

TPS = Throttle Position Sensor

TPMS = Tire Pressure Monitoring System

This thread has been re titled for clarity, and, moved to the appropriate sub-forum

What was the DTC # since the description is surprising.

 

[trixie10]

We got two errror codes P0316 and P0741.

Thanks again for the help.

The P0316 is a misfire detected in first 1,000 rpm after startup.

The P0741 is a Torque converter clutch circuit performance problem or the solenoid is stuck off.

Neither code seems pertinent to the tire pressure monitoring system, nor to the throttle position sensor.

Based upon your original post, it would appear the P0316 is the actual issue, and the P0741 is not relevant to your after start problem. A possibility with the P0316 is the crankshaft position sensor being problematic. It is usually a cheap and easy replacement but I am not sure on the Explorer. I will see what is involved with the V6 and V8. Which engine do you have?

 

[Town]

Here is the diagnostic for the P0316: http://www.obd-codes.com/p0316 The CKP is used for ign timing, but in the first few revolutions of the engine the PCM is looking for the signal at very low revs and if the signal is not received the fuel injectors are turned off. Is your starter turning the engine over quickly?

Here is the procedure to replace the CKP on a 2007 V6:

Removal and Installation

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02 .

Disconnect the crankshaft position (CKP) sensor electrical connector.

Remove the bolt and the CKP sensor.

To install, tighten to 10 Nm (89 lb-in).

NOTE: Be sure the sensor wiring is routed away from the battery cable.

To install, reverse the removal procedure.


Here is the procedure to replace the CKP on a 2007 V8:

Removal and Installation

With vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02 .

Remove the accessory drive belt. For additional information, refer to Section 303-05 .

Disconnect the A/C compressor coil electrical connector.

Detach the battery cable retainer from the A/C compressor stud bolts.

Remove the nut and detach the A/C tube bracket.

To install, tighten to 10 Nm (89 lb-in).

Remove the stud bolts and position the A/C compressor aside.

To install, tighten to 25 Nm (18 lb-ft).

Disconnect the crankshaft position (CKP) sensor electrical connector.

Remove the bolt and the CKP sensor.

To install, tighten to 10 Nm (89 lb-in).

To install, reverse the removal procedure.

If you would like to do the replacement yourself PM me for more detailed procedures with diagrams showing positioning info. Or I can describe the location for you.

Good luck.

The car starts fine just chugs a bit at the beginning then smooths out quickly. Once running everything is fine until you shut off enginen then same thing all over. We have a V6 and I will attempt to change the CKP myserlf. I hate to ask but what does "PM me for more detailed procedures" mean?

A PM is a private message. It allows sensitive info like e-mail address, etc to be exchanged without risk of spam.

I have the procedure to replace the crankshaft position sensor (CKP) in pdf form with diagrams.

Good luck.
