Trouble Code: P1101



Intake Air Flow System Performance

Possible Causes:



A steady or intermittent high resistance of 15 ohms or greater on the ignition 1 voltage circuit will cause the MAF sensor signal to be increased by as much as 60 g/s. To pinpoint this condition perform a voltage drop test on the circuit.
 
Any type of contamination on the MAF sensor heating elements will degrade the proper operation of the sensor. Certain types of contaminants act as a heat insulator, which will impair the response of the sensor to airflow changes. Water or snow can create the opposite effect, and cause the signal to increase rapidly.
 
Depending on the current ambient temperature, and the vehicle operating conditions, a MAF sensor signal circuit that is shorted to the IAT signal circuit will increase or decrease the MAF sensor signal that is interpreted by the ECM. Additionally it may cause a rapid fluctuation in the IAT Sensor parameter.
 
A skewed or stuck engine coolant temperature (ECT) or IAT sensor will cause the calculated models to be inaccurate and may cause this DTC to run when it should not. Refer to Temperature Versus Resistance .
 

Trouble Code: P1106

HO2S Insufficient Switching Sensor 1

Trouble Code: P1174



Fuel Trim Cylinder Balance

Possible Causes:



The Fuel Trim Cylinder Balance diagnostic is very sensitive to HO2S design. A non-OE sensor or an incorrect part number may set a false DTC.
 
Monitoring the misfire current counters, or misfire graph, may help to isolate the cylinder that is causing the condition.
 

Trouble Code: P1336



CKP Sensor System Variation Not Learned

Possible Causes:



Set the parking brake and block the drive wheels for safety.
 
Verify the hood is closed.
 
Read the trouble codes. If a code is set, refer to that code.
 
Start the engine. Allow engine temperature to reach at least 158°F (70°C). Then key off.
 
Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle.
 
Apply the brake pedal firmly and verify the selector is in Park.
 
Increase accelerator pedal position until fuel cutoff is reached at the test RPM (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (RPM) decreases back to idle speed and the procedure terminates.
 
Read the trouble codes and recheck for DTC P1336.
 
If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.
 

Trouble Code: P1362



ICM Control Circuit High Input

Possible Causes:



IC timing signal is shorted to system power
 
IC timing control circuit and IC timing signal circuits are shorted
 
IC module is damaged or it has failed
 
ECM has failed
 

Trouble Code: P1380



Misfire Detected, Rough Road Data Not Available

Possible Causes:



Use the Freeze Frame/Failure Records data to help find the cause on an intermittent fault. If the code cannot be duplicated, the data in the Freeze Frame/Failure Records can determine how many miles since the code set. The Fail Counter and Pass Counter can also help determine how many ignition cycles the diagnostic reported a pass or a fail. Operate the vehicle within the Freeze Frame conditions (i.e., load, engine and vehicle speed, temperature etc.). This will isolate when the code set.
 
Service the ABS before diagnosing a misfire because an actual engine misfire may or may not exist. Also, an actual engine misfire may have occurred during an ABS malfunction.
 
Determine if the vehicle was driven on a rough road, and the ABS could not detect this due to a malfunction. The ECM may interpret variations in crankshaft speed caused by the rough road as a misfire without an actual engine misfire present.
 
Refer to Diagnostic System Check for Antilock Brake System
 
Refer to Diagnostic System Check for the Engine Controls
 

Trouble Code: P1381

Trouble Code: P1516



Throttle Actuator control (TAC) Module Throttle Actuator Position Performance

Possible Causes:



A low voltage condition may set this DTC. Reviewing the Freeze Frame/Failure Records may be beneficial in diagnosing this concern.
 
This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test .
 
A powertrain relay that is slow to switch on may set this DTC. Inspect the relay thoroughly
 
A low voltage condition may set this DTC. Inspect for proper battery voltage and correct charging system operation.
 
The throttle valve are spring loaded to a slightly open position. This is referred to as the rest position.
 
The throttle valve should not be completely closed nor should they be open any more than the specified amount.
 
The throttle valve should move open and to the closed position without binding under the normal spring pressure.
 
The throttle should NOT be free to move open or closed WITHOUT spring pressure.
 
Replace the throttle body if any of these conditions are found.
 



The scan tool has the ability to operate the throttle control system using Special Functions. Actuate the throttle valve using the throttle blade control function located in the Throttle Actuator Control (TAC) System menu. This function will operate the throttle valve through the entire range in order to determine if the throttle body and system operate correctly.
 
Inspect for the following conditions:

Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
 
Poor connections at the ECM or at the component--Inspect the harness connectors for a poor terminal to wire connection. Refer to Testing for Intermittent Conditions and Poor Connections for the proper procedure.
 
For an intermittent condition, refer to Testing for Intermittent Conditions and Poor Connections .

Control Module Long Term Memory Performance

Trouble Code: P1629



Theft Deterrent Fuel Enable Signal Not Received

Possible Causes:



DTC P1629 is an indicator that the challenge/response was not received within the required time. This does not necessarily indicate a fault is present with the TDM or ECM. Factors such as a long engine crank, a delay in the serial data communication, or B-codes set in the TDM will cause DTC P1629 to set. This DTC should not be used as a fault indicator, but rather as a symptom to assist in the diagnosis of these other systems.
 

Trouble Code: P1630



Theft Deterrent Learn Mode Active

Trouble Code: P1631



Theft Deterrent Fuel Enable Signal Not Correct

Trouble Code: P1632



Theft Deterrent Fuel Disable Signal Received

Possible Causes:



The prerelease password sent to the ECM by the TDM is reliant on the communications between the transponder located in the vehicle key and the TDM. Failure to establish communications or an interruption in the communications between the vehicle key and the TDM will cause the fuel disable message to be sent and the setting of DTC B1632. DTC B3055 or B3060 will be set in the TDM. To properly diagnose DTC P1632, DTC B3055 or B3060 must be diagnosed and corrected first.
