Here is the second one. There is a 3rd but it only applies to 08 and 09 rubbing around number one fuel injector.

#PIC4125B: Reduced Power Message Or Long Crank No Start On The First Key Crank - keywords 2.2 2.2L 2.4 2.4L battery cooling crankshaft dead DTC drain draw engine extended fan hard harness key lamp L61 LE5 light - (Nov 17, 2008)


Subject: Reduced Power Message or Long Crank, No Start On The First Key Crank


Models: 2006 - 2007 Chevrolet HHR

--------------------------------------------------------------------------------

This PI was superseded to combine information from AIC3193 due to both concerns coming from same harness issue. Please discard PIC4125A.


--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A customer may bring the vehicle in with a Reduce Engine Power message on the DIC. Any of the following codes may set:

P2120: Accelerator Pedal Position (APP) Sensor 1 Circuit

P2122: Accelerator Pedal Position (APP) Sensor 1 Circuit Low Voltage

P2123: Accelerator Pedal Position (APP) Sensor 1 Circuit High Voltage

P2125: Accelerator Pedal Position (APP) Sensor 2 Circuit

P2127: Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage

P2128: Accelerator Pedal Position (APP) Sensor 2 Circuit High Voltage

P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation

In addition, on vehicles with the 2.4L LE5 Engine (VIN Code P) only, the following codes could also occur:

P0651: 5 Volts Reference 2 Circuit

C0561: System Disabled Information Stored

P0326: Knock Sensor (KS) Performance

P2135: Throttle Position (TP) Sensor 1-2 Correlation

P0335: Crankshaft Position (CKP) Sensor Circuit)

It has also been reported that the cooling fans may run constantly due to this condition.

Recommendation/Instructions:
It has been identified that the engine harness may contact the purge solenoid bracket, causing harness damage and exposing the wires.





Inspect the harness and repair any necessary wires and secure the harness away from the bracket to prevent harness from grounding on the bracket.

 

There is another place, not in the two posts, at least on the '06 2.4, it's a bracket used in line assembly, on the back side of the rear cam cover.

 

So this does not pretain to or include P1818 but I will double check my harness for these contact points, thanks to BQS4 and to Lucky, for this info!!

 

i have a 2006 hhr 2.4 and the ecm trans fuse has blown twice, car wort crank/start , could this be the problem ??

 

Maybe. It doesn't take much to just look at the wires, It is not something you need a MBA for just eyes and fingers.

 

Hi Guys,

I'm Back for a while.

Wouldn't a harness part number tell you if the applications are the same?

Just a thought.
