This could be tough without looking at the vehicle? But I'll see what I can do. First, What year is the 5.4 out of? You replaced the engine wiring harness also? It this plug part of the engine harness or the truck harness? What color are the wires?

How to Replace a p1355 on a 2000 volkswagen new beetle


Is this for a ignition coil output stage open circuit? If so you need to rerun the ground wire. Just but the wire close enough to the coil that you can still get to the wire and splice another wire to it. Just splice a wire to the brown wire and run the rest of the wire to a ground lug under the battery. You will need to remove the battery and the tray. Also when you hook the battery back up make sure the key is on. This will reset alarm and radio. Remember, you are grounding the coil so the wire should go from the coil to ground. Hope this helps

1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.

Hi, I own a Dodge Neon 2005, Came home from a week vacation to find a Rabbit had decided to eat through 3&4 spark plug wires and the coil pack wire harness. unfortunately I didn't know this before...


Hi,
I would be looking around for any other munching by varmits. Your ecm is under the hood. Critters could have taken out more wiring. look under battery area and ecm area for starters.

P0031, ho25circuit low, bank 1 sensor 1. sft b1 -3.91, ltft b1 .78, stft b2 -3.91, ltft b2 3.91. R&R ox sensor or what


Hello,
P0031 - Bank 1 Heated Oxygen Sensor No. 1 Heater Circuit - Low Voltage. That is what this code means.
DTC P0031 is set when Bank 1 HO2S No.1 heater current is less then .09 amps, or potential difference between heater positive and negative terminals is more then 13.99 volts while HO2S heater is on. MIL (The engine light) is illuminated when Engine Control Module (ECM) detects malfunction during 2 consecutive drive cycles.
Possible Causes are: - Bank 1 HO2S No. 1 heater circuit malfunction - Bank 1 HO2S No. 1 heater malfunction - ECM malfunction - HO2S heater relay

DTC Confirmation Test (Advanced/Intermediate Users): Ensure intake air tempature is 18f (-8c) or more, engine coolant tempature is 18-230f (-8-110c) and vehicle is at an altitude of 8000 feet or below, and barometric pressure is 75 kPa or more. Turn ignition off, connect scan tool and turn ignotion on. Using scan tool, clear DTCs. Start engine and run at idle speed for 5 minutes. Using scan tool check for current or pending DTC P0031.

Diagnosis & Repair Procedure (Advanced/Intermediate Users): 1. If engine system check has been performed, go to the next step. If engine system check has not been performed, do the system check.
2. Turn ignition off. Disconnect Bank 1 HO2S No. 1 4-pin harness connector. Bank 1 HO2S No. 1 is located in the left exhause pipe before catalytic convertor. Measure resistance between Bank 1 HO2S No. 1 pigtail connector terminal No. 3 (Green wire) and No. 4 (Blue wire). Resistance should be 5.0-6.4 ohms at 68f (20c). If resistance is as specified, go to next step. If resistence is not as specified, replace HO2S. After repair repeat DTC Confirmation Test (Above).
3. Disconnect HO2S heater relay. HO2S heater relay is located on the left fender well. Turn ignition On. Measure voltage between ground and HO2S heater relay socket cavity No. 3 (Black/White wire). Also measure voltage between ground and HO2S heater relay socket cavity No. 1 (Blue/White wire). If voltage readings at both measurements is 10-14 voltes, go to step 5. If voltage readings are not as specified go to next step.
4. Check for blown HO2S (15-amp) or IG COIL (20-amp) fuses. Fufses are located in the underhood fuse and relay boxc. If fuses are okay, check for open or short it to ground in Black/White wire between IG COIL fuse HO2S heater relay. If problem is found repair as necessary. After repair repeat DTC Confirmation Test (Above).
5. Turn Ignition off. Install HO2S heater relay. Dicsonnect ECM 30-pin harness connector C51-2. ECM is located under instrument panel, under glove box. Measure voltage between ground and ECM harness connector C51-2 terminal No. 4 (Green wire). If voltage reading is 10-14 volts, subsitute a known-good ECM, and repeat DTC Confirmation Test (Above). If DTC does not reset, testing is complete. If voltage readings are not specified, go to next step.
6. Check for short to ground in Green wire between Bank 1 HO2S No. 1 and ECM. If no problem with wiring is found, replace HO2S heater relay. If problem persists after repairs, subsitute a known-good ECM and repeat DTC Confirmation Test (Above).

I hope this helps and is what your looking for. Best of luck.

Sounds like a body control module --in most newer cars there is a ecm for the elctronics for the motor and a bcm for all the interior dudadds --Check EVERY fuse in the truck and out under the hood -- look up the wire color codes for the ecm harness --check the power wire going to the ecm for 12v --or jump a wire off the batt + to that wire to feed it.try to locate all the grounds also--if need be google it --Like my ls1 trans am has a ton of ground wires --but there are 2 on the back of the head--if they are loose it will not run even tho all the other grounds under the hood are tight.I think they do that to isolate the ecm from ground back feeds or cross wireing when jump starting.
