DTC B1E3A 03: Sensor Power Circuit Voltage Below Threshold
DTC B1E3A 07: Sensor Power Circuit Voltage Above Threshold
There are a lot of other qualified repair shop's besides the Dealer .
Oil pressure
Remove the oil sender unit and fit a pressure gauge , start the engine and check pressure, seems odd the oil light and pressure gauge both showed a fault at the same time, perhaps the oil pump relief valve stuck open for a short time.
Turn signal relay 2007 Avalanche ltz
There is no turn signal relay or flasher , Computer controlled by the BCM - body control module .
Turn Signal/Hazard Lamps
When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation. The driver door switch and passenger door switch also receive voltage from the BCM turn signal supply voltage circuits for the mirror turn signals. The door switches have no function or control of the mirror turn signals other than a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. The instrument panel cluster (IPC) receives the signals to activate the turn signal indicators over the GMLAN serial data system. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators.
This is something best left to a qualified repair shop that has a professional type scan tool . Could need new BCM , which would need programming . Scan tool would be able to check switch inputs for BCM .
Where is.turn signal relay
There are only fuses. The relay is built into the hazard switch. But usually it is the turn signal switch that is bad.
No oil pressure
hook up live gauge to be sure you have press if press good r/r press switch when checking with live gsuge dont run engine long as it can ruin it
Front breaks lock up,while driving,park for a few minutes,breaks are fine
Could be that the callipers are jamming or the wheel is running tight. Check for wheel spin with the front wheels off the ground, they should spin with minimum effort. Could also be something wrong with the master cylinder. It may not be releasing properly and slowly building pressure to lock the brakes. After sitting for a while, it returns to normal position and releases the brakes. Mt Ford had a dud wheel bearing which would intermittently start to seize. When this happened, the anti lock braking system thought that the wheel was about to lock and would throw the brakes on and off without warning... Check your wheel bearings too.
How to fix traction control>
Traction control doesn't shut the engine off. It will shut off the ABS system. Which is for slipping and sliding. You need to have the codes read. You can get code readers fairly cheap now days. But the cheaper ones will not read the ABS system or any other. Just the engine.
