Same exact F*cking problem! I just spent nearly $500 at the dealer who said "all was good". WTF now?? Third time now, who knows about Lemon Laws??

and as you paid for...

wasting my precious cell phone mintues. The service rep at the dealership said that he was concerned with the water pump. Apparently, when they diagnosed the car, the tech said the water pump wasn't spinning. If the water pump is bad, doesn't that make the car inoperable?? Plus, the damn thing isn't overheating! This is so maddening. I'm selling and getting a Civic.

(Note the "Effects of Failure" section)


Engine Coolant Temperature (ECT)
Sensor G62 and Engine Coolant
Temperature (ECT) Sensor
(On Radiator) G83

These sensors both operate as negative
temperature coefficient (NTC) sensors. The
coolant temperature set points are stored in
the Motronic Engine Control Module J220
in the form of maps.

The actual coolant temperature values
are registered at two different points in
the cooling circuit and indicated to the
Motronic Engine Control Module J220 in
the form of a voltage signal.

* Coolant actual value 1 is measured at
the cylinder head coolant outlet by
Engine Coolant Temperature (ECT)
Sensor G62 located in the upper level of
the coolant distributor housing.
* Coolant actual value 2 is measured at
the radiator by Engine Coolant
Temperature (ECT) Sensor (On Radiator)
G83 before the radiator coolant outlet.

Signal Utilization

Comparison of the specified temperatures
stored in the maps with the coolant actual
value 1 temperature gives the pulse-widthmodulated signal for the application of
voltage to the heating resistor in the Map
Controlled Engine Cooling Thermostat F265.
Comparison of the coolant actual values
1 and 2 is the basis for activation of
the electric Coolant Fan V7 and Coolant
Fan -2- V177.

Effects of Failure

If Engine Coolant Temperature (ECT)
Sensor G62 fails, a defined substitute value
of 203°F (95°C) is used for coolant
temperature control and the first fan speed
stays activated.

If Engine Coolant Temperature (ECT)
Sensor (On Radiator) G83 fails, the control
function remains active and the first fan
speed stays activated.

If a certain temperature threshold is
exceeded, the second fan speed is
activated.

If both sensors fail, maximum voltage is
applied to the heating resistor in the Map
Controlled Engine Cooling Thermostat F265
and the second fan speed stays activated"

fix anything. If they dispute this, its time to get AoA, BBB and a lawyer involved.

I just spend $500 on if the problem was not fixed? I'd be asking why I had to pay that kind of dough on stuff that did not have to be fixed.

This is part of my ongoing saga.

Funny thing is, anything I've heard or seen says P1296 means general Coolant system malfunction, but their printout stated "Manufacturer Contrl. Fuel Air Metering"

Is there software incorrect? The guy then proceeded to tell me he thought it was the MAF sensor and wanted me to buy a can of cleaner.

I wanted them to scan so dealer can't pull the 'different fault' b/s in an attempt to avoid their screw up from the first time. Thoughts? This could get nasty!
