2009 Cadillac dts cracks but won't start


Cranks but won't start , cracks ! that's funny ,sorry ! Are there any lights lit on the dash , SECURITY etc.....
Engine Cranks But Does Not Run
Circuit/System Description
This Engine Cranks but Does Not Run is an organized approach to identify a condition which causes the engine to crank but not start. This diagnostic directs the technician to the appropriate system diagnosis.
This diagnostic assumes the system voltage levels are adequate for starter motor operation. Refer to Battery Inspection/Test , and Engine Cranks Slowly . Fuel level and fuel quality should be determined for correct diagnosis.
Special Tools ?€¢
CH-48027 Digital Pressure Gage


?€¢
J 26792 HEI Spark Tester


Crank the engine for up to 30 seconds. Observe the Engine DTC information with a scan tool.
?‡'
If any of the following DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle to diagnose those DTCs P0201-P0208, P0230, P0335, P0336, P0340, P0403, P0404, P0601, P0602, P0603, P0604, P0606, P0607, P060D, P062F, P0641, P0651, P0685, P0689, P0690, P1516, P2610.

Ignition OFF for 90 seconds, determine the current vehicle testing altitude. Ignition ON, observe the scan tool MAP Sensor parameter. Compare the parameter to the Altitude Versus Barometric Pressure table. The MAP sensor pressure parameter should be within the specified range indicated in the table.
?‡'
If the reading is not correct for your altitude, diagnose the MAP sensor. Refer to DTC P0106 .

Install a J 26792 . Crank the engine for 15 seconds. Spark should be observed from the Spark Tester.
?‡'
If spark is not observed refer to Electronic Ignition (EI) System Diagnosis .

Important: Additional DTCs may set when using the fuel pump output control.
Command the fuel pump ON and OFF. Fuel pump should energize when commanded ON and De-energize when commanded OFF
?‡'
If the fuel pump does not respond refer to Fuel System Diagnosis .

Turn OFF the ignition. Install the CH-48027 . Turn ON the ignition and command the fuel pump ON while observing the CH-48027 . Refer to Fuel Pressure Gage Installation and Removal . The fuel pressure should be between 384-425 kPa (55-61 psi).
?‡'
If the fuel pressure is not within 384-425 kPa (55-61 psi), refer to Fuel System Diagnosis .

Inspect for the following conditions:
?€¢
Compare the actual engine coolant temperature to the ECT parameter.


?€¢
Air filter and air intake system for restrictions and obstructions


?€¢
Test the fuel for contamination. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .


?€¢
Inspect the spark plugs. Refer to Spark Plug Inspection .


?€¢
Test the exhaust system for restrictions. Refer to Restricted Exhaust .


?€¢
Engine mechanical conditions such as worn timing chain gears, low compression, etc.--Refer to Engine Compression Test .

Battery saver comes on battery light wont start like low battery started 5 min before code p062f comes up


Since you give no make , model or year of vehicle, I will assume it is fairly new if it has a battery saver feature. New cars are programmed to shut down non essential components to conserve power to start a vehicle that has marginal voltage to start the engine. Seems your battery is dying and your car is warning you that it may not start if the problem is not attended to ... Have your electrical starting system checked. Battery alternator, and load check.. Replace battery or alternator if needed.

Code po62f


The TCM monitors itself by using a watchdog circuit and by various software monitoring functions. If there is a fault,
a P0613 is stored. The flash ROM is checked using a checksum calculation. If the checksum is incorrect, a P0605
fault will be stored. The EEPROM is emulated in the flash ROM. If it is not possible to store information in the
EEPROM emulation or if the verification fails, a P062F fault is stored and the ECM is requested to illuminate the
MIL immediately. If the diagnostic software tries to enter two contradictory failure mode strategies or if there are
contradictory output states commanded versus the expected output states, a P0701 fault is stored. It's time to visit the Dealer.

Error code p062b 2012 equinox


Had the same problem on our 2012 Equinox today. Threw codes P026B and P062F. Appears to be a bad battery. Replaced battery and all seems ok now...keeping fingers crossed. My suspicion is that the faulty, dying battery caused a low voltage situation in the injector control module and thus those errors. Will see if the check engine light returns in the next 48 hours.

Received code P1400 engine light on what would cause this code?


GMC Truck Envoy - 2WD ' Envoy, Rainier, TrailBlazer, Ascender (VIN S/T) Service Manual ' Document ID: 1655997

DTC P1400
Diagnostic Instructions
• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor:
DTC P1400: Cold Start Emission Reduction Control System

Circuit/System Description
The catalytic converter must be warmed to efficiently reduce the emissions. The cold start strategy is to reduce the amount of time it takes to warm the catalytic converter. During a cold start, the engine idle speed is elevated and spark timing is retarded to allow the catalyst to warm quickly. This diagnostic monitors the following to build an exhaust energy model:

• Engine speed
• Spark advance
• Throttle position
• Engine airflow
• Engine coolant temperature
• Engine runtime
• Park/neutral position
• Vehicle speed

The actual model is then compared to the expected exhaust energy model.

Conditions for Running the DTC
• A cold start has been detected.
• The vehicle speed is less than 2 km/h.
• The engine is at idle with no input from the accelerator pedal.
• The airflow per cylinder is greater than 80 mg/cylinder.
• DTCs P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0201, P0202, P0203, P0204, P0205, P0206, P0300, P0335, P0336, P0351, P0352, P0353, P0354, P0355, P0356, P0502, P0506, P0507, P0601, P0602, P0603, P0604, P0606, P0607, P062F, P0641, P0651, P1101, P1516, P1682, P2101, P2119, P2120, P2122, P2123, P2125, P2127, P2128, P2135, P2138, P2176, P2610 are not set.
• This DTC runs for 15 seconds within the first 70 seconds of start up. This diagnostic runs once per trip when a cold start has been determined.

Conditions for Setting the DTC
The actual exhaust energy model does not match the expected exhaust energy model.

Action Taken When the DTC Sets
• The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
• The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

Conditions for Clearing the MIL/DTC
• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
• Clear the MIL and the DTC with a scan tool.

Diagnostic Aids
Any loading of the engine that lowers engine RPM, such as with partial application of the clutch, during the first 70 seconds of engine run time may set this DTC.
Circuit/System Verification
Allow the engine to cool. Monitor the Cold Startup parameter. This should indicate Yes. Start and idle the engine for at least 2 minutes. DTC P1400 should run and pass.

Circuit/System Testing
• Inspect the air intake system for the following:
- If any other DTCs are set, diagnose them first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
- Modified, damaged, or restricted
- Dirty or deteriorating air filter element
- Crankcase ventilation system for correct operation--Refer to Crankcase Ventilation System Inspection/Description.
- Water intrusion
- Vacuum leak and other un-metered air downstream of the mass air flow (MAF) sensor
- Intake manifold leak

• Inspect the exhaust system for the following:
- Water intrusion
- Exhaust leak
- Damaged, restricted, modified or enhanced exhaust system--Refer to Symptoms - Engine Exhaust .

My 2007 chevy hhr is giving me check engine code P062F. What does it mean? How do I fix it?


P062F = Internal Control Module EEPROM Error = the memory chip inside the ECM has been fried. You will have to replace the ECM.
