Can a bad or lazy VGT solenoid cause a P132B code? I just recently had the turbo cleaned and the VGT solenoid replaced about 3 months ago. The truck is a bit sluggish at take off. Is there anyway to check the solenoid to see if its bad? Thanks for any help.
You absolutely do NOT want to try and clean the solenoid.
You must have an 03 motor in your truck? Do you know when the last time it was flashed? Usually this code is related to an aftermarket intake. Other things you can do: pull the EBP sensor, check it for corrosion, and clean the EBP tube. Check the map sensor rubber tube from passenger side of the intake manifold to the map sensor and make sure the tube and nipple in the manifold are clean. Do you drive the truck rather conservatively?
Note: Diagnose all other DTCs before diagnosing P132B. Note: For DTC P132B, allow the engine to idle for 5 minutes with engine oil temperature (EOT) greater than 81°C (178°F). Clear the DTCs. Repeat the self-test. If DTC P132B is retrieved again, continue diagnosis of P132B.
Perform a visual inspection.
Connect the scan tool.
Key on, engine off (KOEO).
Retrieve and record any continuous and on-demand DTCs.
Run the engine until the engine temperature stabilizes.
KA2 CHECK THE MANIFOLD ABSOLUTE PRESSURE (MAP) AND BAROMETRIC PRESSURE (BARO) SIGNAL ACCURACY
Note: Route the pressure gauge hose to the passenger compartment so it is not crimped and does not come in contact with any hot surface. Note: Diagnose any EOT sensor DTCs before continuing with this step.
Inspect the MAP sensor hose and manifolds for damage, leaks, restrictions, and correct routing.
Disconnect the MAP sensor pressure hose from the sensor.
Install the pressure test adapter kit 014-00761 0-30 psi gauge between the MAP sensor and the pressure hose.
Access the PCM and monitor the MGP and EOT PIDs.
Allow the EOT to reach 70°C (158°F) and road test the vehicle.
REFER to the appropriate pinpoint test to continue sensor diagnostics.
KA4 CHECK THE TURBOCHARGER OPERATION BOOST
Note: Additional DTCs may set during the use of output control (OSC). Clear all the PCM and transmission control module (TCM) DTCs after the diagnostics are completed. Repeat the self-test to verify all DTCs are cleared.
Key ON, engine running.
Access the PCM and monitor the MGP, EGR DC, RPM and VGTDC PIDs.
Access the PCM and control the EGRDC, RPM, and VGTDC PIDs.
Increase the commanded engine speed to 1,200 RPM using output state control. The calibration may limit the actual RPM between 1,150 and 1,200 RPM.
Decrease the EGR duty cycle (EGR DC) to 0%.
Decrease the VGT duty cycle (VGTDC) to 0%.
Record the MGP PID value.
Increase the VGT duty cycle to 85%.
Record the MGP PID value.
Decrease the VGT duty cycle to 0%.
Record the MGP PID value.
Is the MGP PID below 3 kPa (0.44 psi) at 0% VGT duty cycle and above 6 kPa (.87 psi) at 85% VGT duty cycle?
NOTICE:The VGT actuator valve is sensitive to contamination. All work areas must be clean before starting this procedure. Do not allow contamination to enter the valve ports, cam follower, or turbocharger housing. Handle the VGT actuator by the solenoid body only. Do not attempt to clean or wipe oil off the valve at this time. Do not let the valve come in contact with materials that could contaminate the valve mechanism.
Key in OFF position.
VGT Actuator connector disconnected.
Remove the VGT actuator from the turbocharger assembly.
VGT Actuator connector connected.
Key ON, engine OFF.
Access the PCM and control the VGTDC PID.
Apply light pressure to the cam follower (tip of the actuator), while commanding the VGT duty cycle and check for the internal valve movement.
Increase the VGT duty cycle to greater than 70%.
Is any internal valve cam follower movement present when the VGT duty cycle is increased?
Yes its a 03 engine, I have cleaned the EBP sensor and tube they were not that dirty.
I havent checked the map sensor rubber tube yet. I drive the truck every day and pull a 24ft trailer about 4 to 5 times a year. Dont haul anything that often. Thanks for the info......
Im sitting in the same boat on my 03 right now. I've had the P006A P0401 codes since doing my EGR delete a year ago, but the P132B just popped up a couple weeks ago out of the blue while trucking down the highway.
It starts fine, runs fine, not sluggish, but need to determine the cause.
