Cleaned throttle body, now p0507 code

06 WK Overland w/ 5.7L

Changed out water pump & thermostat recently and saw dirty throttle body so wiped it down. I got the CEL now. Runs good, just have a light on.

I tried clearing the code by disconnecting battery. Light comes back on after a day or so.

I don't want to start buying parts for the heck of it. Do I need to see the stealership?

Re: Cleaned throttle body, now p0507 code

Sorry about that, I didn't see the subject line...

P0507-IDLE SPEED PERFORMANCE HIGHER THAN EXCEPTED

For a complete wiring diagram Refer to Section 8W.
Theory of Operation



The objective of the Idle “Speed Rationality is to monitor the ability to achieve and maintain a steady idle condition. The monitor will judge the functionality of the idle speed control system by monitoring RPM during idle. If RPM does not come within a calibrated deadband of target idle speed, a timer is started. If the timer reaches its maximum threshold without any sign of the RPM trending towards control, a soft failure is generated.
  • When Monitored: With the engine running at idle, MAF <250 mg/tdc, air temp >-17.8 C (0 F) and <-7 C (19.4 F) enable after coolant temp >70 C (158 F) or air temp >-7 C (19.4 F), coolant temp >-7 C (19.4 F) <130 C (266 F), canister purge <100% duty cycle, and no VSS, MAF/MAP, ECT, TPS, ETC, CRK Sensor DTCs nor any fuel system or injector DTCs.
  • Set Condition: Engine speed is 200 RPM or more above idle speed for 7 seconds. Two Trip Fault. Three good trips to turn off the MIL.
Possible Causes
AIR INDUCTION SYSTEM
VACUUM LEAKS
THROTTLE BODY
PCM


Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).



Diagnostic Test

1. ACTIVE DTC

Ignition on, engine not running.
With a scan tool, select View DTCs.

NOTE: Check for any Bus Communication DTCs. If no Bus or Communication DTCs are set, check for active DTCs stored in the Anti-Lock Brake Module. Any bus or communication DTCs or VSS DTCs in the Anti-Lock Brake Module must be properly diagnosed before continuing.

Start the engine.
Allow the engine to reach normal operating temperature.
With a scan tool, select View DTCs.

NOTE: It may be necessary to drive the vehicle to meet the conditions to set this DTC, try to repeat the conditions in which the fault originally set by reviewing the Freeze Frame data.


Is the DTC Active or Pending at this time?

Yes
  • Go To 2

No
2. AIR INDUCTION SYSTEM

Inspect the Air Induction System for the following problems.
Restrictions: Dirty Air Cleaner, Foreign material trapped in the air intake tube, etc.
Leaks: Air Intake tube connection, Air Cleaner housing, etc.

Were any problems found?

Yes
  • Repair or replace as necessary.
  • Perform the POWERTRAIN VERIFICATION TEST. <A href="file:///N:/2007%20Jeep%20Service%20Manual/en_US/y2007/wk/si/xml/extxref_0900000360.xml">(Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
  • Go To 3
3. VACUUM LEAKS

Start the engine.
Inspect the vehicle for external vacuum leaks.
Inspect the engine for internal leaks.

Were any vacuum leaks found?

Yes
  • Repair the vacuum leak as necessary.
  • Perform the POWERTRAIN VERIFICATION TEST. <A href="file:///N:/2007%20Jeep%20Service%20Manual/en_US/y2007/wk/si/xml/extxref_0900000360.xml">(Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
  • Go To 4
4. THROTTLE BODY OPERATION

Inspect the throttle body for carbon build up, other restrictions, and a bent throttle plate using a straight edge.
If the throttle plate does not close entirely it may be bent and needs to be replaced.
Verify that the throttle cable between the Accelerator Pedal and APPS is not binding.

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.

While the vehicle is running, lightly tap on ETC Motor, with your hand, and listen for idle to fluctuate.

Were any problems found or did the idle fluctuate while tapping on the ETC Motor?

Yes
  • Repair or replace as necessary.
  • Perform the POWERTRAIN VERIFICATION TEST. <A href="file:///N:/2007%20Jeep%20Service%20Manual/en_US/y2007/wk/si/xml/extxref_0900000360.xml">(Refer to 9 - ENGINE - STANDARD PROCEDURE)

No
  • Go To 5
5. PCM
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.

Were there any problems found?

Yes
  • Repair as necessary.
  • Perform the POWERTRAIN VERIFICATION TEST. <A href="file:///N:/2007%20Jeep%20Service%20Manual/en_US/y2007/wk/si/xml/extxref_0900000360.xml">(Refer to 9 - ENGINE - STANDARD PROCEDURE)

No

What scan tool do you need? Do it have to be the dealership one?

Re: Cleaned throttle body, now p0507 code

Yeah, that's the one. You checked for vacuum leaks, throttle plate, cable, for issues? Given the description of the code, is it idling high? What else have you done in maintenance and/or troubleshooting?

All I did was replace water pump & install new thermostat. While the air intake was off, I wiped off the throttle body butterfly valve. Now that it is clean, I get the error P0507. I didn't touch/disconnect anything else.

I ran some seafoam thru the brake booster vacuum line about 1 week into getting the code. No change from that.

I did use throttle body cleaner. Didn't see the warning about using throttle body cleaner until after I cleaned it. I am afraid I need to buy a new throttle body because of cleaning it. Is this something I can just install or does the dealer have to do a calibration with the computer?

Re: Cleaned throttle body, now p0507 code

From what I understand, high idle is usually caused by a vacuum leak. Have you had any luck on resolving the code and issue?

Re: Cleaned throttle body, now p0507 code

Still no luck. I have the p2110 in addition to p0507.

Looks like I need the dealer to diagnose it. Wish I could just scan it at home. There should be an App for that.

Re: Cleaned throttle body, now p0507 code

P2110 - Electronic Throttle Control Forced Limited RPM

Possible Causes
THROTTLE PLATE STUCK
(K124) ETC POSITIVE CIRCUIT OPEN
(K126) ETC NEGATIVE CIRCUIT OPEN
(K124) ETC POSITIVE CIRCUIT SHORTED TO GROUND
(K126) ETC NEGATIVE CIRCUIT SHORTED TO GROUND
ETC MOTOR
PCM


Turn the ignition off.
Remove the Air Cleaner Assembly from the Throttle Body.
Check for any signs of a foreign material (ice or dirt) causing the Throttle to stick.
Manually open and close the throttle plate using your hands.

There's a few electrical issues noted as well as possible causes...

Too much to paste, and too many diagrams... You might sign up to alldatadiy.com to get more info.

Re: Cleaned throttle body, now p0507 code

Update: Last weekend I ordered a new throttle body. On Monday morning, the CEL was not on. It did not come on all week. However, I did have the electronic throttle light & traction control lights come on when turning off the cruise control one time. This put me in limp mode.

Installed new throttle body today. Noticed a vacuum line that runs from air filter box to oil filler cap area had slipped off by the oil filler cap. This was hard to see with the plastic hemi cover in the way.

Have not driven it yet. I wonder if the throttle body was ok? I guess with 96 k miles, it isn't a bad idea to replace it as preventive maintenance.

Re: Cleaned throttle body, now p0507 code

I am having this now. Wondering if the throttle body replacement worked??

I cleaned my throttle body by spraying throttle body cleaner on a toothbrush, and scrubbing while I held the valve open, wiped it up after I broke all the junk free. That was about 150 miles before the light came on, P0507, P2101, P2110.

I cleaned the throttle body the same time I put new plugs in. I did the plugs and cleaned the throttle body because my jeep sometimes cranks over more than normal before starting. It still does this. The jeep runs great after it starts, even with the light on.
