U2897 Packard 300 OBD Code

OBD/2 U2897 error code description and symptoms.

HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw.
The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM.

Circuit High Input codes like U2897 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

U2897 Packard 300 Error Code Repair Process :

If your fuel trim too rich (bank 2) check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U2897 and engine control unit are in charge of monitoring a bunch of different fuel trim too rich (bank 2), and if they get a reading that's a little out of whack, up pops the check engine light.

Difficulty Level (Easy)

Repair Time (45 Min.)

Cost Prediction : $ 80-120

A common cause of code U2897 is the failure of Fuel Trim too Rich (Bank 2), but there are several other possible causes as well, such as ;

• Exhaust tube
• Faulty Crankshaft Position Sensor (POS)
• Faulty oil control valve (OCV)
• Faulty Variable Camshaft Timing (VCT) position solenoid

U2897 is a kind of Network Trouble Code U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
