P1A88 PSA - Reversible alternator: Prohibited value of the limitation of the energising current, voltage, temperature or operating status of the alternator

Reversible alternator: Prohibited value of the limitation of the energising current, voltage, temperature or operating status of the alternator. The cited PSA workshop reference documents P1A88 as "Reversible alternator: Prohibited value of the limitation of the energising current, voltage, temperature or operating status of the alternator" for the Continental SID 807 injection ECU (DV6C 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

P1A88 is a manufacturer-specific code. In this database it is documented for: PSA. The same number can mean something different on other brands.
