Question about 1997 Oldsmobile Bravada

1 Answer

I have a open or shorted condition on the shift solenoid circuit

I have a 97' bravada and I took it to auto zone and they said it was a solenoid circuit and did not know what I need to do to fix the problem.

P0753, p0758 and p91860 what's my problem and how do I fix it?


Your best bet would be to take your vehicle to a ASE certified professional . You do not have the tools to diagnose this or the information.
DTC P0753
The 1-2 shift solenoid (1-2 SS) valve controls transmission fluid pressure acting on the 1-2 shift valves to position the valves for the appropriate gear. The 1-2 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 1-2 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 1-2 SS valve is commanded ON, the PCM senses low voltage. When the 1-2 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio .
If the PCM detects a continuous open, short to ground or short to power in the 1-2 SS valve circuit, then DTC P0753 sets. DTC P0753 is a type B DTC.
DTC P0753 sets when one of the following conditions occurs for 5 seconds:
Condition 1 The PCM commands the solenoid ON and voltage feedback remains high, B+.
Condition 2 The PCM commands the solenoid OFF, and the voltage feedback remains low, 0 volts.
DTC P0758
The 2-3 shift solenoid (2-3 SS) valve controls transmission fluid pressure acting on the 1-2 and 2-3 shift valves to position the valves for the appropriate gear. The 2-3 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 2-3 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 2-3 SS valve is commanded ON, the PCM senses low voltage. When the 2-3 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio .
If the PCM detects a continuous open, short to ground or short to power in the 2-3 SS valve circuit, then DTC P0758 sets. DTC P0758 is a type A DTC.
Conditions for Setting the DTC
DTC P0758 sets when one of the following conditions occurs for 5 seconds:
Condition 1 The PCM commands the solenoid ON and the voltage feedback remains high, B+.
Condition 2 The PCM commands the solenoid OFF and the voltage feedback remains low, 0 volts.
What's this p91860 , no such code .

I have 2004 gmc envoy xl 5.3 engine the code po753 is showing up


You are starting to have a transmission problem. I know....the Envoy runs fine....well, this code is telling you that there is a beginning of a problem with your transmission system. It could be a wire, could be a rock that was ran over flicked up under there and possible damaged something.....
Bottom line, there is a an issue developing. Suggestion? Check with AAMCO...it is free and they can give you an idea what the seriousness is.
Trouble Code: P0753 (5.3L V8 VIN P Auto)
A/T 1-2 Shift Solenoid Circuit Malfunction (4L60-E, 4L65-E)
Trouble Code Conditions:
Engine runtime over 5 seconds, system voltage at 10-18v, engine not in Fuel Cutoff mode, and the PCM detected an unexpected voltage condition on the A/T 1-2 Shift solenoid circuit.
Possible Causes:
  • 1-2 shift solenoid connector is damaged, loose or shorted
  • 1-2 shift solenoid control circuit is open or shorted to ground
  • 1-2 shift solenoid control circuit is shorted to system power
  • 1-2 shift solenoid is damaged or has failed
  • PCM has failed

I have to error code with my jeep grand Cherokee Laredo 1999 the code are 1491,1495,753,136


P1491 Rad Fan Control Relay Circuit An open or shorted condition detected in the radiator fan control relay control circuit. This includes PWM solid state relays.P1495 Leak Detection Pump Solenoid Circuit An open or shorted condition detected in the Leak Detection Pump (LDP) solenoid circuit.P0753 (M) Trans 3-4 Shift Sol/Trans Relay Circuits An open or shorted condition detected in the overdrive solenoid control circuit or Trans Relay Circuit in JTEC RE transmissions. Was MIL code 45. P0753 (M) Trans 3-4 Shift Sol/Trans Relay Circuits An open or shorted condition detected in the transmission 2-4 shift solenoid circuit (4-speed auto. trans. only).P0136 (M) 1/2 O2 Sensor Heater Circuit Malfunction Oxygen sensor heater element malfunction.

Aside from getting into an accident and having your wiring harness severely damaged, the other likely suspect is your PCM. These codes are not related to each other and indicate a much larger problem.

I took my 200 honda accord to auto zone to get a diagnostic done. the code was p1259. the ticket printout listed 4 things that would be probable cause. 1.open or short circuit condition 2.vtec solenoid...


CHECK VTEC SWITCH OIL PRESSURE.SHOULD BE 50 PSI @3000 RPM FOR THE S2000 OIL PRESSURE SHOULD BE 85 PSI @ 3000 RPM. IF OIL PRESSURE OKAY HAVE TO BE EITHER VTEC SWITCH FAULTY OR VTEC SOLENOID HAS FAILED.SOME TIMES PCM HAS FAILED TO THAT CONTROL CIRCUIT.

Torque convertor clutch circuit electrical code po743


CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic pressure
acting on the lock–up relay valve, which then controls the operation of the lock–up clutch.
DTC No. DTC Detection Condition Trouble Area
P0743
 ECM detects open in solenoid SL circuit 4 times when solenoid
SL is not operated (2–trip detection logic)
 ECM detects short in solenoid SL circuit 4 times when solenoid
SL is operated (2–trip detection logic)
 Open or short in shift solenoid valve SL circuit
 Shift solenoid valve SL
ECM
Fail safe function
If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF

06 Corolla Pressure Control Solenoid D Electrical Fault


There is a technical service bulletin to correct this condition. Replacement of the car's Electronic Control Unit (the computer) will cure this. Take it to a Toyota dealer and have them replace it for free.

I don't know how the above could have any effect on temperature. Is the vehicle full of coolant? In my opinion you have two different issues

Troubleshooting code PO753 ECM or PCM.


It is more likely the solenoid, the PCM is very seldom the problem, about 3% of the time to be exact.
