On a gt225 where is the battery discharge sensor located?

Do you know ?
*: ECM determines the start signal status by the signals of engine speed and battery voltage. The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.
The relay is located in the IPDE E/R under hood fuse / relay box . Should show location on inside of lid

Camshaft Position Sensor Replacement (5.0L, 5.7L)

Removal Procedure

Caution: Refer to

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

For Vehicles equipped with OnStar® (UE1) with Back Up Battery:

The Back Up Battery is a redundant power supply to allow limited OnStar® functionality in the event of a main vehicle battery power disruption to the VCIM (OnStar®module). Do not disconnect the main vehicle battery or remove the OnStar® fuse with the ignition key in any position other than OFF. Retained accessory power (RAP) should be allowed to time out or be disabled (simply opening the driver door should disable RAP) before disconnecting power. Disconnecting power to the OnStar® module in any way while the ignition is On or with RAP activated may cause activation of the OnStar® Back-Up Battery (BUB) system and will discharge and permanently damage the back-up battery. Once the Back-Up Battery is activated it will stay on until it has completely discharged. The BUB is not rechargeable and once activated the BUB must be replaced.



1. Disconnect the negative battery cable.



2. Disconnect the spark plug wires and ignition coil wire from the distributor.


3. Disconnect the CMP sensor harness connector from the distributor.



4. Remove the distributor cap screws.



5. Remove the distributor cap.



6. Remove the rotor screws.



7. Remove the rotor.
   


8. Remove the CMP sensor screws.



9. Align the square slot in the reluctor wheel with the CMP sensor.



10. Remove the CMP sensor.
    

Installation Procedure

Important: Do not use the old cap screws, CMP sensor screws, or rotor screws. Use replacement screws that have been coated with a thread locking compound. Precoated replacement cap and CMP sensor screws can be acquired using P/N 10475922 (pkg of 10 screws). Precoated replacement rotor screws can be acquired using P/N 10475924 (pkg of 10 screws).

1. Align the square slot in the reluctor wheel with the CMP sensor.



2. Insert the CMP sensor through the reluctor wheel slot.

Notice: Refer to Fastener Notice in Cautions and Notices.




3. Install new CMP sensor mounting screws.
   
   Tighten:
   
   Tighten the fasteners to 1.6-2.8 [n-m] (14-25 lb in).
   

Important: The locating tabs on the rotor are necessary for correct alignment of the rotor. If the tabs are missing or damaged, replace the rotor.



4. Install the rotor onto the reluctor wheel.



5. Install new rotor fasteners.
   
   Tighten:
   
   Tighten the screws to 1.5-2.4 [n-m] (13-22 lb in)
   


6. Install the distributor cap.



7. Install new distributor cap screws.
   
   Tighten:
   
   Tighten the screws to 1.8-3.0 [n-m] (16-26 lb in)
   


8. Connect the CMP sensor harness connector.


9. Connect the spark plug wires and ignition coil wire.



10. Connect the negative battery cable.

Take the truck to Autozone or Oriely auto parts and have them test the alternator, it is free.

Trace the intake from the filter toward the engine. There should be a black object with electrical wires coming out of it before the intake reaches the turbo. Now you have found it, what are you going to do with it?
the first thing to try if you suspect problems is clean it thoroughly but carefully. See multitudes of YouTube videos on what to do.
after cleaning, disconnect both leads off the main battery and then touch them together for 20 seconds. This completely discharges all electricity from the ECUs.
connect the battery again, start the motor and let the ECU learn where idle is, then drive it as normal.
Any further problems get the trouble codes on the computer scanned.

knock sensor located on the side cylinder block below intake manifold.

Sounds like a bad temperature sensor. Fairly cheap and easy to replace. Could also be a bad relay but I would start with the sensor first.

There are two sensors; Climate Control Sun Sensor located on the dash or rearview mirror, and an Ambient Air Temperature Sensor located by the climate control panel. I believe the one you're looking for will be the Ambient Air Temperature Sensor.

Try to locate the frontal sensor as this the terminals usually get corroded.Disconnect the battery and wait for 2 minutes before doing any repair just to discharge the backup power of the module.

Try to locate the cause of the discharge current as below:-

While vehicle electrical system shutdown as for overnight storage, connect an ammeter (with suitable current capacity and sensitivity) across the main ground connection between the battery -ve terminal and vehicle chassis/frame - (-ve of the ammeter to -ve battery terminal post, +ve to vehicle frame),
Carefully disconnect the main battery ground cable from the chassis,
The ammeter will now measure the battery discharge current - a discharge current in the order of 0.5 amp or more is of concern.
If all is well, the current draw should not exceed 50- 100 mA.
Note- Do not switch on any load while ammeter is connected, as ammeter damage or overload will occur.
If an excessive discharge current is observed, remove all fuses etc to eliminate / locate cause.

The voltage of your car's battery and the surge from the other car's battery when you jumped might have been enough to blow the fuse on the electronic speed sensor, or the sensor itself, try locating the fuse box and search for anything to do with sensors or so, if there's nothing wrong there it's the sensor itself, and you'll need to take it to a workshop.
