[V8] ecu code

[Dave Saad]

I had my MIL light turn on today - and the code is 2342, which appears to be for a 4.2 ABH motor according to http://www.sjmautotechnik.com/trouble_shooting/ecufv8.html#faultc


Here is what the website says:

2342 Oxygen Sensor Signal (voltage) is not changing up and down, (Shown for ABH Engine Only)
Signal shorted to ground or to +12V,

Fuse #5 blown, O2 Sensor heating element not working,

Ground problem between ECU pin 10 and engine block,

fuel pressure too low or too high, intake or exhaust system leak, defective ignition system component,

intake air leak after air mass sensor, O2 sensor is faulty

Overly rich exhaust, Spark Plug fouling,


California vehicles: Check Engine Light should be ON


Is this a valid code for a '91 PT motor too? and if it is, this O2 sensor is about 6 months old.
