Ford 7.3L Power Stroke (1999-2003) :: Codes For Exhaust Pressure Circuit Valve / Intake Air Heater Control Circuit
Jun 14, 2011
I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?

I bought my truck 2 month ago. I use it for commuting, only short trips now ( 10 min ). After about 2 weeks the Check Engine light came on. The truck is running fine, no problems I believe, starts easy. After another 2 weeks, the CEL disappeared. Another week, and the CEL came back on and it`s there since. I have a code reader, these are the codes and meanings according the manual:
P0299 - Turbocharger "A" underboost condition
P2286 - Injector control pressure sensor circuit high
P2287 - Injector control pressure sensor circuit intermittent
P0299 Pending - same as first but with "pending" status
This is my first diesel and my first turbo charged engine. Is this a common problem? How serious? It`s a bit strange that the error came up before but disappeared. Can that happen just because of the short trips I`m making? I`m planning a long trip soon with towing my trailer, so I want to make sure the truck will not break down during the ride.

I have this sensor unplugged. Is there a way to defeat this sensor so I don't pull this code?

Okay, so I have a 14' 6.7L, about 18,438 miles on it and the check engine light came on when I was at the gas station ready to leave, and so I took a field trip to auto zone and they scanned the CEL and it came back as P20BA - Reductant Heater 'A' Control Circuit Performance and they said I need to change out the pump assembly so I took it to the dealership and they cleared the code which worked for awhile, about 4 months ago the light came back on and I'm wonder if I should get the pump/heater changed out or get it deleted? The warranty is going to end in august this year..... It's been fine no issues with the truck, even tho I drive with the CEL on and just wondering what I should do? The CEL has been on for almost 5 months.

2004 Excursion 6.0L .... Recently after a 200 mile trip through the mountains running good, I get home and the next day it idles down the driveway at a high idle and after a few minutes seems to run better but within 5 miles the CEL comes on and throws P2287 - intermittent injection pressure control circuit. I cleared the code, ran around town again and the light came on again same code. I'm getting appropriate ICP-voltage and pressure readings. I took it home sat overnight and thought I would pull the ICP sensor.
I replaced the ICP sensor less than 6 months/5,000 miles ago. I also changed out the main engine harness at the same time. I looked at ICP sensor and it looks clean. Started the truck and tried the scientific wiggle test while running and monitoring ICP-voltage. Started at the sensor bending and wiggling back to FICM. No fluctuation in voltage. Ran the truck around town, 20 miles and no light. Yesterday we made the same 200 mile trip over the mountains, seemed to run strong. In town this morning within 5 miles the CEL is back on and the only code is P2287.
My Ford powertrain diagnostics manual doesn't have the P2287 code in it for troubleshooting. Should I go after the FICM, and how do U test that if so? I'm currently that 200 mile drive from home and don't want to damage anything more.

Engine light came on yesterday and started missing on take offs. Giving code p2285 Injector Control Pressure Sensor Circuit Low. I've done the research and understand the problem. It's the weekend and shops closed until Monday. Is it safe to drive in the mean time? Is there any risk of doing damage? What's the risk of it quitting or failing start in the short term, today?

I understand that exhaust runs through the EGR. what I don't know is:
Does the EGR valve control the amount of exhaust into the air intake?
If so, does only the amount of exhaust let through the valve go through the EGR?
if so, if the EGR valve is closed then no exhaust will go through the EGR?

What can be done regarding these faults? P0037 and P0057
Description:
Oxygen Sensor Heater Control Circuit Low (Bank 1, Sensor 2)
Oxygen Sensor Heater Control Circuit Low (Bank 2, Sensor 2)
The catalytic converters have been removed but the fault was present before that anyway. All I want is the VSC function to work again and the lights to go off. I have heard you can put dummy sensors in.

I need the PCM pinout for a 2002 F150 4.6 For the Purge Control Valve Circuit. If possible the wire schematic would be nice also. Getting code PO443 (( hard code )) I have checked battery voltage at valve connector with key on (( 12.2 volts )) valve resistance is at be 35 ohms so I'm thinking I may have a bad wire or a bad PCM .

I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

OK I'm putting a plow on my truck. I am wondering if it's possible to add more circuits to the fuse box in some of those unused slots?

Finally had a good scan done on my truck at the mechanics. The reoccurring codes were P0478 and P0470. It looks like a bad exhaust pressure control sensor. Looks like an easy fix.

1997 2wd, 4.0 - As you can guess it runs pretty bad at idle. It has O2 heater circuit codes for all 3 sensors. I'm leaning towards the ECM because the 2 heater wires are both hot with the key on. I unplugged the computer and turned the key on and just one wire is hot. Looks like the ecm is supposed to ground the wire to turn the heater on, but it's going hot instead?

The other day my 07 power troke threw codes p2285 and p2287- ICP circuit low and ICP circuit intermittent. The trucks idle was revving up or bouncing around every so often, not consistently.
I did a visual inspection of both the sensor and pigtail checking for oil but it looks to me like everything is clean and oil free (see pictures). When I unplugged the connector the trucks idol smoothed out and everything ran great!
My questions is what does this indicate? Does this mean my ICP sensor is bad, my pigtail is bad, or there is a short in the harness somewhere?

The check engine light came on yesterday. 2004 with 115K. Auto Zone read the codes and they are as follows:
Definition:
Idle Air Control Valve control circuit.
Probable Cause:
Open or short circuit condition.
Poor Electrical Connection
Failed IAC motor

I have a 2006 f-350 6.0 and i went to fill up my truck with diesel. After that the truck did not start. Currently has the code p2285 - injector control pressure sensor circuit low. I tried disconnecting sensor, still no start.
I have the torque pro app and another 6.0 that I use for comparison. Check power at ficm 48 volt, flp 11.5v, FVP 11.5v. Hpop while cranking shows 1400 psi. removed oil filter and see low pressure oil ok, fills up reservoir. ipr at crank about 65%. fuel filter full of fuel.
Replaced the dummy plug on passenger side because originally hpop was very low psi 12. after replacement it went up to 1400 on cranking. What should I be looking at next, should I be removing ipr? should i be looking at crank sensor or cam sensor? Just installed 2 new batteries also because my dad kept cranking the truck until it died.
Checked to make sure fuel cut off relay not triggered, Ok. The truck has been having long cranks before it died. Also right now the injector cycling is 10 seconds long while on my other 6.0 it is about 4.

Just got back from the beach yesterday. On the way back I noticed the check engine light on and read the codes. It listed 4 codes, P0671,P0672, P0677 and P0678. From what I can find, Cylinder 1, 2, 7 and 8 have the glow plug circuit open. Truck ran fine and didn't miss a beat. Ambient temp was around 80 when we started up the truck so I guess diesel plugs are not to crucial for that temp. I did notice when driving back the Vbatt would jump from 12.2v at1854 RPM (34 MPH) and 13.8v at 1652 (57 MPH).
Would bad batteries or low batteries cause this type of problem? This may be wishful thinking on my part. I have tested the batts with a DMM and they are at 12.3v. I took them out and charged them but they always go down to 12.3v. FMP is 47.5v to 48.5v. It seems suspect that all four glow plugs would be bad so I assume it could be the harness. What are some ways I can test to verify where the problems come from.First thing I would do is get two new batteries as these are still under warranty.

I have a 1996 Ford Explorer Eddie Bauer Edition 5.0, the check engine light is on and my code reader gives P0161 and P0155 both stating that the O2 heater circuit sensor is bad. I replaced all 4 of the O2 sensors in the truck, cleared the codes but they still keep coming back. I have tried for a few days now to find something online similar to this but have had no luck. I am not sure what else to do.

So i just finished putting in new high pressure oil rail cup seals in and a new #2 injector. Truck was running great for about 5 miles and then just shut off. When I had it towed home I plugged in the super chips tuner "no tunes installed" and I have a p0460, p0463, p2290, p2291. I also have a #7 glow plug circuit failure Ive been a little neglectful in getting done.

I have a 2007 f-250 6.0 liter turbo diesel. I was pulling a trailer with a golf kart on it and was not in tow haul. I was going up a hill and it shot up into 5th gear. I pulled into my house and shut it off and refired it and it acted fine. I went on a little test drive to see if it was going to do it again before I went on my trip. As soon as it shifted into third gear the tow haul light started to flash on my dash and went to 5th gear and would not down shift even if I did it on the column.
I scanned the truck with my snap on modus and it gave me these codes. P0706-transmission range sensor A circuit range/performance, P0707-transmission range sensor A circuit low input, and P1702-transmission range sensor circuit intermittent. I put a transmission harness in it and started it up and it ran fine and the codes were gone. I went for a test drive around the neighborhood and as soon as it hit 3rd gear it did the same thing as before. Today I put the old one back in and checked the codes so I could write them down and there weren't any so I went for a drive and it shifted through all the gears great and downshifted fine as well.
I pulled into my drive way to check for codes once again and there weren't any. I was gonna go for a ride in tow haul to see if it would do it and as soon I put the truck in reverse it started to idle high and the tow haul light started to flash again. I put it in drive to pull back into my drive way and it immediately shifted into 5th gear and threw the same codes...

My check engine light has came on and I received these error codes
PO441 : Evaporative emissions control system incorrect purge flow.
PO 455 : Evaporative emissions control system pressure leak-large leak.
PO 446 : Evaporative emissions control system vent control circuit fault.
Also only my driver side fan is working, may be separate issue?
