I recently replaced the coils the icm cam sensor and crank sensor and still getting a p1350 code on my 94 lesabre . how can i fix this please?.?


DTC P1350 Bypass Line Monitor
Refer to Ignition Control, Knock Sensors .

Circuit Description
The Ignition Control Module (ICM) sends signals that the PCM requires for fuel control and spark advance calculations. At the start of engine crank, the ICM controls spark advance (Bypass mode.) When the second 3X reference pulse is recognized by the PCM, the PCM applies 5 volts to the Bypass circuit, commanding the ICM to switch spark advance to PCM control (IC mode). An open in the IC circuit or a short to voltage in the Bypass circuit at startup will cause the PCM to monitor IC pulses during crank, when the ICM should be grounding the IC circuit. This condition will set DTC P1350. The engine may be started but will run on Bypass mode timing.

Conditions for Setting the DTC
The PCM monitors IC pulses during crank while Bypass mode spark advance is commanded

Action Taken When the DTC Sets
The PCM will illuminate the malfunction indicator lamp (MIL) during the second consecutive trip in which the diagnostic test has been run and failed.
The PCM will store conditions which were present when the DTC set as Freeze Frame and Failure Records data.
Conditions for Clearing the MIL/DTC
The PCM will turn OFF the MIL during the third consecutive trip in which the diagnostic has been run and passed.
The History DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
The DTC can be cleared by using the scan tool.
Diagnostic Aids
Check for the following conditions:

Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the ICM, turn the ignition ON and observe a digital multimeter connected between the IC circuit and B+ while moving connectors and wiring harnesses related to the ICM. A change in voltage will indicate the location of the malfunction.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

Test Description
Number(s) below refer to the step number(s) on the Diagnostic Table.

This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed.

1989 jeep grand wagoneer 360 how do i test bad crankshaft position sensor


double posted, now with 360, 5.9L V8 fact.
great.
and has no such sensor.
its a CARB car
with ICM , spark magic box. , NO ECU /PCM brain in car
there for no CKP sensors.. sorry?

if you dont know what is there, photo it and post it
so others can see what is missing or wrong, from factory day 1 build.

i google for you
rockauto shows no such part in 360
alldata.com same
hell. even the 90s the same.
see it here.
all schematics

if engine wont start. even with test fuel, check spark
see the spark section below, under ignition.

http://oljeep.com/gw/elec/GW_wiring-1990.html

the distributor has cam sensor. not crank.
it called today, CMP, cam sensor
this sensor sends signals to the ICM the ICM then makes spark
buy driving the coil,
the CMP is more like Points, simulation, and lasts near for ever.

the 89 4L has a CKP (crank sensor) and is know to fail on brand new cars. (you need to tune it to make work , back in 88/89) at flywheel.
ask me how in know./././??


360 spark
CMP >>>>> ICM>>>> COIL>>> Dizzy cap>>> spark plugs.
this is the chain of events.
the DIZZY does the ADVANCING with ICM. totally. on this car.

I am expriencing the same problem on 2004 Grand Prix. Did you vere find a solution?


Since you have "check engine" light turn on, will need scanner the PCM to know what fault code is stored there; with this code number could send you additional details, Sound like a emissions problem.

Keep in touch.

You can't just change the crankshaft postion sensor an expect it to work correctly > Has to have
Crankshaft Position System Variation Learn done !
you need a factory scan tool Tech 2
Install a scan tool.
Monitor the powertrain control module for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC.
Select the crankshaft position variation learn procedure with a scan tool.
The scan tool instructs you to perform the following:
4.1. Accelerate to wide open throttle (WOT).
4.2. Release throttle when fuel cut-off occurs.
4.3. Observe fuel cut-off specification for applicable engine.
4.4. Engine should not accelerate beyond calibrated RPM value.
4.5. Release throttle immediately if value is exceeded.
4.6. Block drive wheels.
4.7. Set parking brake.
4.8. DO NOT apply brake pedal.
4.9. Cycle ignition from OFF to ON.
4.10. Apply and hold brake pedal.
4.11. Start and idle engine.
4.12. Turn A/C OFF.
4.13. Vehicle must remain in Park or Neutral.
4.14. The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
• Crankshaft position (CKP) sensors activity--If there is a CKP sensor condition, refer to the applicable DTC.
• Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC.
• Engine coolant temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature.
Enable the crankshaft position system variation learn procedure with the scan tool and perform the following:
Important: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.

My blower motor won't shut off


I had the same issue. Brought it back to dealer and they replaced the blower itself. Below is the bulliten


Models:
2005 Buick Allure (Canada Only), LaCrosse
2004-2005 Pontiac Grand Prix

Supercede:
This bulletin is being revised to update Step 5 of the service procedure. Please discard Corporate Bulletin Number 05-01-39-001 (Section 01 - HVAC).
Condition
Some customers may comment on an inoperative or intermittent Heating, Ventilation and Air Conditioning (HVAC) blower motor. Others may comment that the blower motor speed may momentarily drop or that the blower motor continues to run after the key is turned off.
Cause
This condition may be caused by a voltage spike from the wiper motor. The voltage spike may cause a logic lock up in the blower motor control module that may be either momentary or permanent.

Security light comes on intermintently then car will not start for ten minutes it will do this quite often for awhile then will quit for a long time any ideas that don't cost more than the car is worth?


I have a Technical Service Bulletin. I'll even hand copy it from my program.

TECHNICAL

Engine stalls, Security Lamp illuminated, DTCs (Replace Theft Deterrent Control Module)

Models:
2000-2003 Pontiac Grand Prix built prior to Vin Breakpoint 3F115058

Condition

Some customers may comment that the vehicle starts then stalls and the security lamp is illuminated. These symptoms may be intermittent and after several attempts, the vehicle may stay running.

Cause

The condition may be caused by either a chafed wire in the theft deterrent module wiring harness or an electrical interference within the theft deterrent module not allowing the fuel enable signal to be detected.

Correction

Replace the theft deterrent module with Part No. 10335045 and reroute the module wiring harness to a new location using the procedure listed below.

1 Reroute the module harness on the outside of the steering column channel and tie strap the lower portion to the larger ignition bundle.

2. Replace the tie strap removed from the tilt head during disassembly. Secure the new strap in the hole in the tilt mechanism and around the module wire and ignition SIR wires, but below the tie strap located on the sir wires.
