Seems that the IPC/BFC ACC fuse is responsible for the instrument gauges not working on your 2004 Pontiac Grand Am 3.8 Liter1. It is possible that the fuse is faulty and needs to be replaced. However, if the fuse is in good condition, there might be an issue with the wiring or the instrument cluster itself. Check the inputs (powers and grounds) going into the cluster with the key on using a voltmeter. Fix/repair wiring as needed or replace the instrument cluster as needed. A qualified mechanic might diagnose this --and a scan tool.
Hi there:The automatic Transmission Fluid Pressure (TFP) manual valve position switch consists of five pressure switches (two normally-closed and three normally-open), and a transmission Fluid Temperature (TFT) sensor combined into one unit. The combined unit mounts on the valve body. The Powertrain Control Module (PCM) supplies ignition voltage for each range signal. By grounding one or more of these circuits through various combinations of the pressure switches, the PCM detects which manual valve position you select. The PCM compares the actual voltage combination of the switches to a TFP manual valve position switch combination chart stored in memory.The TFP manual valve position switch cannot distinguish between PARK and NEUTRAL because the monitored valve body pressures are identical. With the engine OFF and the ignition switch in the ON position, the TFP manual valve position switch indicates PARK/NEUTRAL. Disconnecting the AT inline 20-way connector removes the ground potential for the three range signals to the PCM. In this case, with the engine OFF, and the ignition switch in the ON position, D2 will be indicated.When the PCM detects an invalid state of the TFP manual valve position switch circuit by deciphering the TFP manual valve position switch inputs, then DTC P1810 sets.Action Taken When the DTC SetsThe PCM illuminates the Malfunction Indicator Lamp (MIL) during the second consecutive trip in, which the Conditions for Setting the DTC are met.The PCM commands D2 line pressure.The PCM commands a D4 shift pattern.The PCM freezes transmission adapt functions.The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.The PCM stores DTC P1810 in PCM history during the second consecutive trip in, which the Conditions for Setting the DTC are met.Since the computer does not know what gear range the transmission is shifted into, it defaults to a higher line pressure to protect the transmission. It also commands the transmission as if it were in the D4 position. The transmission will still shift normally through all the gears, shifts may be more firm than normal. No damage will occur to the transmission if driven even for prolonged periods with this dtc set. It is far more likely that the loss of transmission fluid damaged the transmission.Hope helps.

TWO duplicates deleted! Refresh page to see your question. You can't Bypass Security and Immobilizer, it is there to stop exactly what you are trying to do. You have to fix it, not find a way around it. Two computers and a security module are there to stop you.
The first thing is to reset it. Is the antitheft light on?
Or you call an auto electrician

Turn the key to the on position for 10 minutes then turn off, repeat 2 more times. the system should reset. Mine usually resets on the second time, if the security light stops flashing then i try to start. My mechanic told me it takes three times to reset but it never has on my car, good luck.

it means that you're traction control is disabled. You are now able to spin tires/burn out. If you do not want to do that, locate the button to turn it back on... usually it just says TRAC on the button, usuallly located towards the bottom of the dash.
The traction off and on button is on the center face of the dash, justabove the radio and is the left button, the right button is your emergency flashers. It says ETS on the button.
2.2L Engine & 2.4L Engines These engines are not equipped
with rocker arms. The camshafts directly actuate the valves.
3.1L Engine & 3.4L Engines When install or connect the check the following: - Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32
Nm).
- Rocker arm cover using a new gasket. Torque the rocker cover bolts
to 89 inch lbs. (10 Nm). - Heater bypass pipe. Torque the screw at the water pump to 106 inch
lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25
Nm) and the nut to 18 ft. lbs. (25 Nm).
About the INTAKE MANIFOLD... - Intake manifold nuts and bolts and tighten to 89 inch lbs. (10 Nm) - Pushrods and rocker arms. Torque the bolts to 89 inch lbs. (10 Nm)
plus an additional 30 degree turn.
- Lower intake manifold. Apply sealant to the threads of the bolts
and torque the bolts to 115 inch lbs. (13 Nm).

injector pressure sensor ???? It doesn't have anything like that, it has a fuel pressure regulator - vacuum operated . Hook up a scan tool and check for codes or take it to a qualified repair shop. Quit trying to play auto mechanic.
